If you haven't read "Careless People", you should. Peoples lives, governments, politics have been altered so facebook can grow and build its influence.
The least one can do is to say all that.
fair. but I think e.g. nitpicking about the FB rename to Muse distracts from the genuine points and makes the statements seem emotionally charged which makes it easier to dismiss
and I think there's also a point to be made that you shouldn't be too caring about issues that you can't influence, it simply causes harm toward yourself.
you already know what will happen. if the model is good enough, people will use it.
you're asking for a lot of things here. I don't think most people take it that personally.
