I haven't left because I was concerned about the data they were collecting, I left because I realised that I couldn't stop going on facebook, any time my hands were free I would open up my phone and check the feed, scroll through the endless stream of garbage and crap I didn't care about in the slightest. That, and the fact that I was getting really depressed by all the news surrounding brexit, then I would go and read comments and be completely negative about everything, and facebook was just amplifying the negativity tenfold.
I just cut the cord and I am now a lot happier without it, facebook is literally a drug,
I shifted to Twitter for a while and eventually kicked that too. I get the HN daily digest email and generally only visit the links from that, though there are exceptions when I'm looking for something interesting over morning coffee (hence replying to this post at this time). I stopped paying attention to the news media years ago.
I think I'm pretty much free of the 'need' to look at what's 'new' now. You might think this means I have loads more free time to do more important things. I'm still waiting for that to happen.
