Because their hosting companies aren't your competitor. Just because they have the same general brand name slapped on the label doesn't mean they are one company. At the same time, even if it were a competitor: does it matter? Your service superiority isn't based on whose computers it runs on, as long as it runs well.

Say it's about the money: then yes, you could in theory have a problem with that, but one way or the other you'll have a problem: if you work at zoom and someone has an xbox, uses windows or uses office you're still tied to that 'competitor'. It seems to me that the competitor is just that specific element (Teams, Skype) and not everything that happens to be close to me. But I'm no MBA and my perspective is probably not the most profitable one.
