I'm the "main tech guy" of a financial firm and I can answer this question. It's because people like me don't care about user experience. We get Teams for free in our M365 subscription. It's integrated with other stuff, it has APIs for automation and I can't be blamed for choosing MS. I know this is a shitty argument... but seriously, I have many battles to fight, not wasting my energy choosing the best chat software. Devs think a lot a about software quality and stuff, but that's often irrelevant for business. GP is wrong, MS knows exactly what they need to do to increase profits.
