It's overly naive to think that people who use such a tool choose to use it.

In many cases it's "you are hired into this job, this is the tool we give you, if you don't like the tool, take a hike".

Even more so, a lot of software is developed not to be competitive, but to be exclusive. It's a lot easier to be the only choice for doing something than trying to compete with a different tool. I've seen countless examples of tools developed in exactly this paradigm, where the decision to use the tool wasn't made by anyone anywhere close the users of the tool (eg. hospital procurement department buying a PACS or a large avionics company ordering a custom-made budget-management program).

Come on now, you were never told in your career, not once, "we use Microsoft Teams for communication here"? Ever?

Most crappy software exists because of inertia and corporate policies. If people truly had a choice stuff like MS Teams could be phased out by the end of the next quarter.
