I had some dickhead coming at me the other day on Lemmy for not having completely erased Facebook from my life. As though that's a remotely reasonable thing to expect everyone to do.
It's not like making a personal decision not to use Amazon or to install Linux. It's a social network. It's literally not possible to make the decision unilaterally, unless you want to cut yourself off from people you care about IRL and from real political organising.
