TV channels don't want you to mute your TV when they display ads, should TVs block this functionality to force you listen to their ad?
Probably because literally every single friend and family member of mine is on there and sharing their entire life there (and messaging me) and I can't take part in that. I said in another comment that once a platform provides that degree of communication, certain rights to protect the users should be applicable, to ensure we are able to participate in society without onerous cost to our mental health, dignity or privacy.
They're welcome to take the servers down altogether, if they can't pay for them without displaying ads.
Or require an API key that's tied to a particular account that pays for access.
