Earlier quoted context omitted.
Posting on Twitter or Mastodon is the equivalent of shouting on a public street. If you don't want to face the consequences of what you say, don't say it publicly (or at least don't do it with your real name).
No — the expectation was never that people would creepily record every corner of the public sphere. That’s anti-social behavior and it’s okay to call it such.
If it wasn't an expectation, then it SHOULD have been. People are allowed to remember and record what you yell on the street, just like they are allowed to remember and record what you post on a public platform for anyone to see.
