Well, there's the PyCon story [0], where two guys ended up getting fired because they made an 'inappropriate' joke among each other in a public space that was overheard by someone else. And there are more stories like this.

So saying anything that might be even remotely offensive to anyone can end up with you losing your job. Based on stories like this, I'm personally afraid of cancel culture. Because this joke is the sort of joke I could've made.
