I agree they should be forced to offer office on Linux. It is one of the things that really keeps Linux down for normal people.
Why should they not be able to offer ads in their own products though? I don't like ads but I do not immediataly see the issue. I think they should absolutly be allowed to do AI but things like only allowing bing chat in Edge should be banned. The amount of pushing they do is clearly not OK. And same for google they should not be allowed to push chrome on you when you go to gmail or google in a non chrome browser
