What exactly do you think is involved in making it “chill for anyone to just pick up this job if they feel it’s their thing”? Like, should anything different be done? Should anything be done at all? Or should we tell anyone who has any criticisms, 'nah we made it chill, so your criticism is actually invalid'?

IMHO any action should not be centered around combing history to formulate a constant moral (istic) judgement on past behavior.

Sure, the most egregious cases of outspoken chauvinism should be addresses - preferably if they relate to something occurring today - but constant nitpick and blanket attack simply select for people with axes to grind who are motivated to quarrel.

Propositive criticisms like "this attitude/prejudice/whatever, today is an obstacle now and we should work to remove it if we care about an inclusive society also in our industry and workplace." would be much more effective (IMHO.)

That is exactly what people are asking for. You just objected to exactly what people are not doing, and called for exactly what they are calling for.
