I work in an advertising-adjacent field (we won’t do any skeevy data-harvesting stuff, but still, ads) and I barely use any of the main social media sites, have an adblocker enabled on my router, use uBlock, GrapheneOS for my phone, Linux with a bunch of hardening, a VPN that’s always on etc.
My work computer doesn’t have any of that 'cause I need to be able to see ads on it, but sometimes if I forget and just browse around on my work computer with no ad protection… holy fuck it always surprises me how awful the internet is.
