“Like, if I tweet or hashtag about how you didn’t do something right or used the wrong verb, then I can sit back and feel pretty good about myself, cause, ‘Man, you see how woke I was, I called you out.’”
“That’s not activism. That’s not bringing about change. If all you’re doing is casting stones, you’re probably not going to get that far. That’s easy to do.”
- Barack Obama

That said, this person stood up for their principles (rightly or wrongly) and lost their job because of it. Your quotation about people "casting stones" in a cavalier way, just to feel good about themselves without it actually risking them anything probably describes a lot of online "woke" flamewars but (to me) doesn't very well characterize what happened here.
