This is absurd. You're just asking for reasonable control over data that ostensibly belongs to you. Moreover, this minimum functionality was resolved years ago with RSS. That you'd be willing to pay so much reflects how well every tech company is doing at using tech against its own users.
Ehhh, what I'm paying for is FB/Insta's ability to bring everyone onto one platform and encourage them to post regularly. RSS, AOL Messenger etc, never were able to do that with any decent success.
That they went past that to just kill their own golden goose is what is now reversible via a payment plan. That might be their only saving grace on this now managed decline.
