This won't happen to everyone, but again, it's a matter of agency. Someone at a tiny startup may not care, but someone at a bigger or more political org might might feel risk differently. It's their career, not TripleByte's.
Right now? None. Because sensibly there is no such publicly available thing.
Any recruiter or hiring manager who doesn't at least look for a candidate's public LinkedIn page (and in those roles, they should also have LinkedIn premium or whatever it's called too) is not doing their job properly.
I have little doubt that this would have become "standard procedure" for managers when prepping for the "forward looking" section of a performance review and when making decisions about promotions/layoffs/payrises - if Ammon had got his way.
