I have tried switching from #Zulip to #MSTeams like some of my colleagues, but I just can't. I have had nothing but problems with Teams and Zulip just works -- with key features that Teams is lacking. In essence, Teams is trying to be a "do everything" app, and wants to pull us in to the MS ecosystem that our parent organization has been all-too-willing to acquiesce. But things like Video Call work terribly*, permissions are complicated, and integrations are hairy, and over-reaching obnoxious.
I guess I'm a fan of "do everything" apps; I must be, with how I use emacs. But also implicit in that is not denying anyone's earlier work, and not solving problems that have already been solved. Zulip builds beautifully on regular #email. Teams wants to replace everything, including email. It the process it has become a massive and over-engineered behemoth where it is hard to get anything done (as a dev) without Microsoft-levels of funding.
@worldsendless At work, we have Office 365 so we ought to use Teams, right, since we get it "for free" with O365? We tried it. We prefer to pay for Slack (in addition to O365) because it just all round works better and has better integrations etc. In the same way we also pay for Zoom because it works better than the A/V and screen sharing in Slack. I would sort of prefer we only paid for one collab platform but none of them on their own work well enough in all cases to supplant the others.
