I have little sympathy for the IT folks, because not only did they make us switch from Slack to Teams because Teams was "free", but they actually drink the koolaid and think Microsoft products are better. They deserve to suffer for the pain they repeatedly cause the rest of us.
There's sadly a subset of IT folks, often in large corps or government, who tend to just drink the Microsoft "Customer Success Engineer" koolaid without thinking. When I worked briefly for a gov org, any time the IT staff came out of a meeting, we would always be worried about what "solution" they had been sold this time.
