There definitely was a point when I thought that, yes, this is a new product and it is looking good, give it another year or so to get the kinks out. But then they removed features they got right the first time, like fullscreen screen sharing with their New Experience. They also added more and more half-baked poducts with rapidly changing apis and the like. From then on I was convinced that they in fact didn't want to learn what Slack/Discord/etc. did right and just go their usual MS way.
