People love to go "bad thing bad", but without actually anything else.

because the ones who have interesting things to say and want to say it for themselves number many, despite being very small in the face of the unwashed masses

Three different groups of people, with some overlap between the first two:

    - people with their own websites
    - privacy activists and /or anti-capitalists 
    - almost everybody on the planet 

I seriously doubt that people who clamor for the death of Facebook and the likes do it so that indie web is full of macha latte labubu car tastings and supplement and gambling shills.
