Yes, I am saying all this in full agreement that there should be requirements for cancellations to be as easy as subscribing, which we have. That said...
Companies are a collection of people. They are not your slaves either.
Saying "I want there to be a mandate that companies auto-cancel my subs if I don't use them" can be re-phrased as "I want a developer somewhere (or a team of them) to be forced (under threat of punishment) to write a bunch of code so that I don't need to do something which is very arguably my responsibility".
