I get where you're coming from (and I've rolled my eyes at the "video games cause violence" line of reasoning myself).
However, there is much wisdom in McLuhan's "we become what we behold" -- and consuming too much "social media" turns one into a performative puppet. Twitter is the distilled version of this (Jaron Lanier called it "Twitter Poisoning").
If Elon Husk huffing Twitter 24/7 while owning Twitter isn't a case of "getting high on your own supply", then I don't know what is.
