I would say the real reason it "works" for non-tech workers is because they don't have enough bargaining power to reject crap such as Teams and similar Microsoft software, and/or haven't had the chance to try out anything else and don't know what an actually good experience is, while tech workers generally do and reject it as a result (that's why this garbage is non-existent in startups and tech-centric companies).
Spinning it as a tool for non-tech workers is a nice cop-out from the truth which is that non-tech workers merely lack the political power needed to reject this shit (and similar - Windows, etc) just like the vast majority of tech workers do. If those non-tech workers were given a choice, Microsoft's marketshare would significantly shrink overnight.
