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.
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.
