At work we started calling this trend clippification for obvious reasons. In a way this aligns with your comment: The information provided by Clippy was not necessarily useless, nevertheless people disliked it because (i) they didn't ask for help (ii) and even if by any chance they were looking for help, the interaction/navigation was far from ideal.

Having all these popups announcing new integrations with AI chatbots showing up while you are just trying to do your work is pretty annoying. It feels like this time we are fighting an army of Clippies.
