My general principle is that private conversation between known entities (like friends & fam) is usually a good thing and something humanity is well adapted to (since that’s how offline has worked for millenia) while anonymous immutable persistent broadcast is danger zone and unlike anything previous generations have had to deal with. Even a skeevy bathroom wall can be cleaned up or painted over.
Both have their pros and cons, of course, and (as always) you’ve got to case-by-case it, and there are good uses of the bad side and bad uses of the good side, and the line between them is often bleedy and blurry, but overall this pretty much aligns with how I see SSH, PGP, SSL as everyday necessities but get skeeved out by “darknet” type stuff.
