I totally get that the network effect makes it difficult to leave abusive platforms, but if one cares enough, it is possible to make that sacrifice. I deleted my Facebook account, for example, and now I can’t keep up with numerous people and groups that use Facebook. It was worth the sacrifice for me.

"If you don't like it, you can simply stop participating in society" is not really a good argument to me, but I'm glad it works for you.
