Irrelevant to the discussed case. When you start vandalizing posters at work it is no longer a case of just "ignoring history".

I think for this specific case it wasn't a vandalized poster, but some writing on a blackboard that was simply replaced. I've seen that at a few startups, the black/white board where everybody should feel free to write whatever, or draw a doodle.

Would you care to answer assuming that it wasn't a case of vandalism?

No, I don't want to spend more time chasing an increasingly stretched hypothetical that is being made to defend what would be asshole behaviour at the best of times.

I can't find a statement threatening to fire anyone, but the message I've seen says "Despite my clear communication at Q&A last week that this was unacceptable, and messages from several other leaders from across the company, this has happened again. I was already very disappointed by this disrespectful behavior before, but after my communication I now consider this malicious as well."

If your boss tells you to stop doing something at work and you keep doing it then yes, that can get you fired, no matter if it's singing Ave Maria or throwing rhetoric against a civil rights movement.
