The key difference, is that the US is many jurisdictions (Federal + 50 states + a lot of others, from counties to cities to territories to MANY others), and the variance amongst those is high.
The key thing well regulated places like Sweden get right, is that in consumer contracts you have minimum bars that you must meet regardless of what you can get the consumer to agree to. So, for instance, return policies, for goods bought online have minimum standards they must meet.
In the US, these things have huge variability. There are well regulated states, and well, the others.
Yes, but Swedish contract law actually is like this. A contract is a specific agreement, it can never be "Oh well, you can add provisions as you like if you send them to me" or "I will pay whatever".
I negotiated my mobile phone or internet contracts again and again, to get better deals. I threaten to leave, they throw a bone. Because they know I have options. Providers who know you don’t will squeeze you however they please.
Like to put it another way how much of this is 'We must do it this way because Americans are simply built different and we're just special' vs 'this makes a handful of people a bunch of money and they have teams of lobbyists, marketers, and lawyers to normalize this kind of stuff in society over time'?
The US's quagmire of incoherent laws and many jurisdictions seems to be a bad combination of:
* Apathetic voters that are raised on a media diet of "big government bad", which impedes any regulations on a federal level. (Note that this is irrespective on if the voters actually want a small government, it's what they're led to believe.)
* Politicians that don't like to give up power; there's an unusual desire for local/state US officials to claim responsibility and get very pissy when the federal government steps in with a standardized solution. This is very unusual compared to other countries; punting responsibilities to local officials in other countries is generally seen as a way for politicians to abdicate responsibility by letting it die in micromanagement and overworked administrative workers and isn't popular to do anymore these days. (This is also a two way street, where federal US lawmakers can abdicate making any legislation that isn't extremely popular by just punting it down to the states, even if they have legal majorities.)
* The US has a court system that overly favors case law rather than actual law. Laws in the US are permitted to be painfully underdefined since there's an assumption that the courts will work out all the finer details. It's an old system more designed around the days of bad infrastructure across large distances (like well, the British Empire, which it's copied from). It's meant to empower the judicial branch to be able to make the snap decision even if there's not directly a law on the books (yet) or if a law hasn't actually reached the judiciary in question. The result is that you end up with a bunch of different judiciaries, each with their own slightly different rules. It also encourages other bad behavior like jurisdiction shopping where people will try to find the judiciary most favorable to them, crafting "the perfect case" to get a case law on the books the way you want it to get judges to override similar cases and so on and so forth - in other countries, what the supreme court judges doesn't have nearly the same lasting impact that a decision in the US has.
* And finally, the entire system is effectively kept stuck in place because lobbyists like it this way; if they want to kill regulation, they just get some states to pass on it and then hem and haw at the notion of a federal regulation. Politicians keep it in place on their own, lobbyists provide them the grease/excuse to keep doing it. (And those lobbyists these days also have increasing amounts of ownership over the US media, so the rethoric about voters not liking big government regulations is reinforced by them as well.)
It didn't end up this way on purpose; the historical reasons for this are mostly untied from lobby interests (which is mostly just "the US is the size of a continent in width", "states didn't actually work together that much at first" and "the US copied shit from the British Empire"), but they're kept this way by lobby interests.
If you have an agreement that says one party can announce changes, you don't have a contract, because those changes were not agreed to.
To me the insane part is that contracts don't have to be registered with the courts (or some qualified third party) ahead of time.
Like each party could show up with their own piece of paper (or not be able to provide it). Which is largely the issue here in that one party is showing up with a 2021 document and the other a 2023 document.
Yes, of course.
We don't have any rules about contracts needing to be written down or registered or anything of that sort. Even verbal agreement are valid, and you are entering into simple contracts even when you buy something in a store.

These users have agreed to a monthly contract or, if there is no money paid, a contract with no finite end date but with provisions to change terms, essentially terminating and restarting. So the service provider has decided to amend the contract at the end of the current (one month) contract in the first case, or on some date arbitrary date in the second (unpaid). The users are free not to accept the new contracts.
So nobody is just changing a contract mid stream. Use of a service month-to-month implicitly agrees to this: your ability to stop using and paying them on the 1st of the next month is their ability to change the terms on which the service is offered next month.
And btw, everyone on here hates this, but I don't know how else it could work. The idea that if I sell a customer one month of a paid saas on a monthly plan I'm somehow obligated to never change my terms or price forever as long as he or she keeps paying is beyond absurd. If people want stable terms, they need to find software that will sell them annual or multiyear contracts.
The US breaking its contract law to treat non-contracts as contracts is one of the most insane things I've seen a legal system do to itself.
