As a forcéd user of Teams, I have to say this, a thousand times over: it _sucks_, I -- and everyone I know -- _hates_ it and it seems to have been rushed out to crush the competition and integrate into Office online products. I also hate these and don't use them, but unfortunately some of my colleagues do.

But, you know what? Nobody cares about my opinion! You are exactly right: the people who make these decisions about what software the university "runs on" are at a far higher level, and have far more clout. Their incentives are totally misaligned with mine -- I use linux as a daily driver, and write highly mathematical software. I am exactly _not_ the target audience of these things, because, frankly, I can support myself: if something's broken, I fix it -- and don't consume IT's time. The people who _do_ however, are all of the admin staff, many of whom have professional backgrounds elsewhere, and think this is the way the world works. And they get promoted, and end up in managerial roles that make purchasing decisions at a high level. Hence, Teams.

Yep. I hate Teams too. It freezes my system for 30 seconds at startup, and spits out 404 Not Found errors sometimes when I log in.

But hey, nobody was ever fired for using Microsoft.
