I'm not sure this is it. Twitter and Mastodon has loads of people who turned some details that would previously been considered intimate or controversial -- transness, sexual preference, polyamory, stance on American partisan politics or Israel vs. Palestine, etc. -- into a major part of their online persona, and are posting either under their own names or pseudonyms that aren't impossible to discover, but without a profit motive.
Only when those details/stances are obviously protected, IME. Consciously or unconsciously, they may be concluding that being visibly a member of a protected class makes you safer from being fired than not being so.
