I don't use facebook and I block their social media buttons. I have less control over friends of mine posting pictures of me on facebook or the fact that facebook is able to read SMS send to peoples phones that have their App installed.

I'm fully aware that people don't care about privacy and abusive corporate practices, which is why it falls on the shoulders of the few that do care to come up with compelling alternatives, that respect users privacy. As you mention those alternatives would probably not be profitable (because you can't rely on ads). If they came in the form of new protocols (just like Email or SMS) and free software to implement those protocols it wouldn't matter as much.
