Idk, I still see Micro$oft used a lot. Maybe not on HN but HN in general being filled with tech employees is often more sympathetic to big tech companies.

MS is betting hard on AI which has earned them this current moniker. If they keep doubling down on this bet I can see it sticking.

I find it interesting that they renamed Office to Copilot, and HN has been pretty quiet about that. It's been clowned pretty hard on other sites.
