A year or so ago I noticed I would wake up and the first thing I did was load up Facebook in my phone. I deleted the app, and what do I do? i still open it on my phone's browser. So I changed my password to 32 characters generated by Keepass, and make sure I logged out of it on my phone. I'm still logged in on the desktop, but nowadays it's pretty quiet anyway. Thr last few days I've been using a Chrome extension (1) to delete stuff from my wall, reasoning that just like real life interactions, it's okay to forget things (well I did download my archive/went through my activity logs and saved them as HTML files).
There's only 1 person I wish to stay in touch that I talk to exclusively on Messenger. I think I will have to persuade them to install another app. Admittedly it will be WhatsApp, which is also Zuckerberg's tool for "dumb fucks".
