'Unthinkable', yes, indeed, they are unaware; unaware of the risks they run by attaching themselves to a platform, unaware of the nature/architecure of the problem, unaware of the sollution.

They "feel" they have no alternative, just as much they "feel" there are issues. Same goes for the audience side, that "feel" there are issues with platforms(the algos, dark patterns etc) and "feel" there is no way out (and why many probably welcome government intervention, if not out of sheer desperation).

Obviously converting the center in a single day is not a thing, but especially these days there is a whole lot there in the margin that is ready for 'capture'; and going back to Williams original post, is a matter of getting the point across
