He’s said worse - which isn’t a defence just an observation, I don’t think this particular outburst will torpedo any contract they had (if they had).
If it’s an issue of recency bias there’s a wider argument to be had on statute of limitations on judgements of character.
By all means replace them though!
As someone who works in marketing, I would say potentially yes. It depends on what they are going for.
If they want to deliberatly generate interests in the new things, they would have just put "new stage info coming soon", but they would potentially want to do this if they want to keep it completely under the wraps and they want to make a big announcement, and at the same time change this page.
This type of update they did takes about 5 hours max, so it's not like they wasted a lot of time.
