Even office isn't that good. It's basically been static in features for 25 years (until copilot came around). It took them a decade to surpass the 65535-row problem in excel. Microsoft get really lazy when they have a virtual monopoly. We saw the same with Internet Explorer. They just left it to whither away until it was too late.
And yeah Teams, I can't stand it. Outlook too, in particular the "new" one that doesn't do half the things the old one could do and requires all your email to be in MS cloud even if you have another provider.
