No I don’t use facebook or twitter. But it’s more for personal disgust than for morals. Nothing you or I or ten thousand lemmings do or not do will change the rising domination of social media on our civilization. Same as our individual choices won’t impact climate change. It’s the same illusion that only serves to prevent actual action against a serious threat. Not even thinking or talking about possible solutions. Corporate control of the means of communication is amoral, and accepting it is problematic.
Maybe I’m wrong and network effects can be overcome through a well crafted alternative like mastadon. But capital translates into power for marketing, development, articles and regulation or even legislation.
