I don't know if breaking up these massive "tech" companies is a good approach, but something has to be done at some point, and there needs to be rules over how YouTube can regulate its platform. At the very least, YouTube needs to be forced to make all of its rules explicit and to not insta-ban entire channels while deleting all their data.
I'll admit though. I'm not so sure what the effect of breaking them up will be. How many services would be lost, how many sites would go down because of lost services, how much money would be lost due to search ranking being ineffective or businesses needing to buy ads from multiple companies. It would hurt a lot of people at least temporarily. But I think long term the Internet and business would thrive after a short term pain. It would definitely have to happen in stages though. Each part of the business broken up into a few.
But yeah I agree, the escape velocity companies you mentioned need to be put in check somehow.
Foregoing vaccination imposes an as-yet-unaccounted externality on the community; you put everyone at risk by not vaccinating yourself or your kids, and there's no way for the vulnerable (those relying on herd immunity) to know who around them will put them at risk.
It goes way beyond an individual choice, to vaccinate or not. That decision has impacts far beyond the individual's life.
You are OK with banning the idea? It's one thing to make it criminal to endanger your children's health. It's another to put a blanket ban on the speech because you don't like the idea or you think it's "dangerous". The point of free speech is that you don't get individuals deciding who gets to be in charge of what is morally right to say. Society as a whole decides through civil discourse and rigorous debate. But you can't have that if you go around suppressing the other side.
Start banning free speech and you start banning democracy. There is really no two ways about it. This is not a debate about the physical choices people make. Those are either made illegal or not. This is a debate about whether or not people have the right to talk about their ideas. But you are here trying to use a ridiculously nearly undefendable action to spin the argument of some actions are bad or dangerous. Yes they are, but the speech and discussion can only enlighten the public so long as reasonable minds have a chance to speak up against unreasonable ideas. Humanity's resilience comes from the fact that we get to try so many ideas at once out. But if you let a single entity decide what ideas will be allowed you introduce a dangerous weak point into society. The inability to speak your mind only ever brings suffering violence and death. Yes free speech has its problems but it's the best we got.
How far are you willing to go when it comes to oppressing individuals in the name of the common good? Force women to have children to repopulate aging countries (or, alternatively, force sterilize them in overpopulated countries)?
Vaccination, for those who can be vaccinated (not everyone can), is a trade-off for participating in a society free from disease. Taxation is the price you pay for buying a society and traffic controls are a price you pay for access to a ubiquitous and generally safe road network.
All of coexisting with others is a balance of trade-offs; labeling all of those trade-offs as oppression renders the word meaningless, as much as referring to any kind of coercion as violence.
As for how far am I willing to go? Mandatory vaccines are a good trade-off, and I am willing to stand by the position (one which is growing increasingly popular, as preventable diseases are returning in force).
Forcing women to have children? I have never heard, outside fiction, of a society that forces women to give birth; certainly it's been encouraged, lionized even, but you're proposing something from the realm of fiction as a what-if. Not helpful.
We will never have absolute safety in life. I prefer to have freedom to make the choice because the government will always end up abusing any power we give it.
I do disagree with your private business comment though. It is a private business and they can do what they want to an extent. You don't tell a news paper who they have to let write articles. But I think the problem is that youtube is so large and the service so imporant that it might as well be a government deciding rights. It's not just youtube there are a lot of tech giants that powerful. I think when it's obvious they are that powerful and important it's time to break them up. I mean hell the bread company my step dad works at even had to go through a process to see if they would be too big with a recent purchase. But yet tech companies have been getting away with this sort of unchecked growth. They are global powers with dwindling competition. Break them up. Reintroduce competition.
