Well you have to look at the math.
Even with the decimation from the loss of "hobbyist" users they will still have a viable business even with a subscriber base of just a few thousand.
Of course that means they will have to try to retain those users by offering a better product.
It also means they can try to retain those users by locking them out of the ability to edit their own content if they were to unsubscribe.
You should probably stop asking for for that. It's just not going to happen.
No company would ever give up that kind of control.
Sadly, more professional, feels a lot less friendly.
