For me: Cancelling paid subscriptions should be as easy as subscribing. I hate the fact that they actively hide the unsubscribe option or that you sometimes should have to write an e-mail if you want to unsubscribe.
Biden administration was working on making that unsubscribe bullshit illegal last year. But then Trump so those tactics will probably be mandatory pretty soon...
Click to Cancel was put in as a rule, but it requires active enforcement. It also had a 180 day grace period from last October, so it hasn't even gone into effect yet.
