I am aware that Facebook has done a bunch of bad stuff, and that they own Instagram and WhatsApp. I still don't give a shit. For all it's faults Facebook is still the most convenient way to keep up with friends and family spread around the world, and share my underwater photography. If you engage with Facebook on your own terms and "hide all from" the news / politics / meme pages then it works great. And it's free!
And no, I'm not interested in doing extra work to set up Mastodon.
