At the same time, backlash is usually an efficient way to force companies to change course

I have serious doubt about that.

Look at facebook, Cambridge analytica, leaks of ton of personal data, again and again, political ingerence, hate content.

I can't remember how many times they said 'whooops my bad, won't happen again', 'oooooh again?! Hahaha whooopsy'

And suckerberg ils still there.
