The primary issue is that many people prepaid for a year of Prime, which included ad-free streaming, and that ad-free service was changed mid-contract. I’d have no problem if the included streaming tier or overall price was changed at renewal.
That's fair, changing mid-year is definitely a problem and arguably illegal under current law, though really if we had functional antitrust I'm not sure that bundling would be legal to begin with.
They rolled out the new ToS to all customers, the original ToS they agreed to when signing up gave Disney permission to do that. There is nothing illegal going on here.
They are assholes that lost my business forever for doing shady shit. I had paid for an annual plan with no-ads. It doesn't have to be illegal to be anti-consumer. I vote with my wallet.
Agreed, good on you for having principles and sticking to them.
There's obviously a limit to what you can change via ToS. Yes, their ToS says they can alter the deal at their discretion. Adding ads to a premium ad-free tier seems like fundamentally a violation of the presumed contract. (Specifically talking about one-year plans, saying that they can make these kinds of fundamental alterations to the deal mid-year sounds like it ought to be illegal if they're selling one-year plans.)
