We use Teams at work. We also use almost everything else Microsoft sells, which is probably the only reason we use Teams. I suspect that the kind of company that uses Teams is just not very interested in critically evaluating Microsoft or competitors (relative to companies that are evaluating specific Microsoft products as one-offs). They're already bought into an ecosystem whose main strength as a collection of mediocre (or worse) software is that it is integrated with all the other mediocre software in the collection. If they don't 'trust Microsoft', where does that leave them? So they 'trust Microsoft', and that's the end of that.
