I deleted my FB/IG accounts in 2014 citing privacy reasons and being tired of social media.
The worst thing about it, and especially the case when you are on the move, is that people are still on these and energy still spent 'with friends' on these. The cost of not being on these platforms is a big social cost.
Now all I have is Twitter which is mainly work and just high noise now. And new places like Mastodon which, while there are nice folks/strangers, is just not the same.
