They might be sadists having the time of their lives. There are few better opportunities in life to get away consequence free with causing pain to a huge amount of people, than working on Microsoft Teams. Not only get away with it consequence free; they're even getting paid for it!

I have not met a single softie who defended the decision to make ctrl shift c the shortcut to start a call in a group chat when ctrl shift v is paste unformatted.

Especially given that the teams client doesn't allow disabling or editing keyboard shortcut.

Microsoft employees may be lazy but unlike Facebook employees (I refuse to call it meta), I don't think they are evil.
