Speaking only for myself, they may be absolutely correct, in their criticism (I know I’m a stuffy old coot, and use “quaint” techniques, like OOP), but I’d suggest that it’s a really bad idea to participate in these fora.
This article is Exhibit A. Three people have just been called out, on the front page of HackerNews, for snarky comments they made, almost a decade ago. I can’t imagine that it’s helpful for their careers. No one wants to work with a bully. I think the author has long since moved on, as I see her GH repos have been basically abandoned, long ago, and I wish her well.
That’s a big reason that I’m a stuffy old coot. Social media can last forever, so I make a point of not engaging in online pissing matches, and being as positive and encouraging as possible, even if it garners me scorn.

[UPDATE] I was interested in what she has had to say, and found this: https://heathermoor.medium.com/what-happens-when-you-retire-...
It appears that she's doing fine, but not really participating so much in open source.
It looks like her detractors are probably also OK.
Don't you just love happy endings?
