None of that is my problem as a user though. I'm not obligated to expose myself to malware so that Coca-Cola can accurately track how many people saw their ad.
A website is currently absolutely within their rights to decline you service if you refuse to be tracked by Coca-Cola's spyware ridden malware. This is a consequence of living in a society dominated by false cries to adhere to incorrectly stated libertarian ideals - regulation isn't all bad, though anti-competitive regulation tends to be bad (there is a grey area with incidentally introducing barriers to market entries to fulfill a social need... like everything - it's complicated).
If Spotify wants to suspend accounts for using adblockers, fine. I don't actually object. But I'm seriously disturbed by the number of comments here which equate using adblocked Spotify with 'stealing music' or otherwise imply that ToS violations are criminal acts. This sort of framing, by people who ought to know better, is why tech companies are still showing up in court pretending ToS violations are felonies under the CFAA. (And, thankfully, getting slapped down by increasingly-annoyed judges who understand the distinction.)
Creating a new copy of something is not the same as stealing the original, blocking ads is not the same as obtaining unauthorized access, security precautions aren't interchangeable with other approaches to adblocking, and violating a EULA is a civil matter.
Just to be clear, libretarianism is not incompatible with regulation - I happen to think that a certain amount of regulation and government oversight is required to allow things to function, I am an optimist about human behavior, but the ideal anarchist world with no laws is absolutely unsustainable, IMO. So my barb (and it wasn't even a sharp one) was more about the false painting of libretarianism being incompatible with government regulation and the talking points that ensue, then any desire to allow a focus on individual freedoms.
The highest-profile appeals to corporate interests are made by politicians who don't claim libertarian ideal. The ability to cut consumers off from non-essential, non-monopoly services for terms violations is standard throughout countries without any libertarian tradition, so the exotic element in the US is the legal protection for spyware creators and malware distributors, neither of which stem from libertarian theory. The spyware aspect is about the lack of a direct constitutional privacy protection, and the conservative/literalist readings which have steadily eroded the penumbra reasoning. The malware aspect is the result of repeated failures to hold companies responsible for allowing data breaches or serving exploits, which owes more to special interests pandering and gross technical ignorance among legislators than to even a pretense of libertarianism.
You're right to say that cutting off service access is legal, and you're right to say that the most influential form of libertarianism in the US is twisted and often counterproductive. But I suspect I'm not alone in finding the attribution of any business-related badness to libertarianism tiring and a bad basis for a productive conversation.
As an aside, isn't it amusing that getting an American education one of the skills that seems to be valued above others is the ability to twist words to whatever B.S. you need them to mean at the time, it's like everyone in the US is an expert marketer and political fixer/spin-man.
The US is incredibly thin on socialism, even nominal socialism, and we already see traces of this when public-interest arguments become convenient. The Net Neutrality fight is a hideously good example; once ISPs decided their monopolies were too blatant to use free market rationales, they went out and astroturfed a narrative where cheap and fair internet was an attack on minorities and the poor.
And yes, I can't deny that US libertarianism (the party and a lot of the individual voices) is weirdly pervaded by a willingness to abandon libertarian principles in deference to corporations. It wasn't that long ago that you could find conservatives complaining about excessive "civil libertarianism" in calls for social progress. Today, it's horribly easy to find people arguing that Wells Fargo should be allowed to stretch their forced arbitration clause to cover outright fraud, because apparently the bank's rights are the only ones which we need to protect.
It is a different landscape now than just buying a primetime slot, advertising is much much more about gleaming any piece of potentially useful personal information about a user for an advertisers own furure use or for sale to the highest bidder. And personally identifiable information held by third parties will never be secure as it is a challenge and a prize for talented people to steal.
Other services like twitch have done what you said and users are equally irate about ads they can't skip and are completely embedded.
Basically it sucks for all parties involved. But at the end of the day you have to monetize or die.
Also I feel a lot of users are voting that 2 coffees a month is too much for music. I'm an old so... but for most of my life music just came out of a box for free. Sure I didn't have much control over it. But when I use spotify I just or pandora or amazon I tend to just get a genre based station going and just let it roll. Just like radio. I don't have time to be futzing around with optimizing playlists and that, I literally just don't care about music very much. Hell one of my friends, when he wants to concentrate, just puts the same song on repeat all day long (8+ hours).
That used to cost: cost free, price of tape/cd ($16 / year way over priced), free(napster,piracy), free with ads (pandora)...
Hell I can't even stomach paying $12 / month to xm when I'm going to drive cross country with no coverage.
