Me and my team use both, Slack and Teams, but only because Slack‘s video call feature is really poor compared to its competitor(s). I never really quite got why Slack dev was not able to at least close the gap to Teams in this area. The video call feature is still buggy and lacks important features, such as inviting externals (by calendar invite) or sharing screen AND video, not to mention a whiteboard. If Slack had been a bit more ambitious in this respect, Teams would never have been an option.
I can vouch that delivering quality, scaled, enterprise video conferencing is a much bigger technical challenge than it seems after, say, a weekend or two hacking with WebRTC in a hobby capacity. It combines the challenge of supporting a huge landscape of differing hardware devices with that of supporting a huge landscape of differing network environments. There's a near-infinite combination of corner cases that can cause problems and handling them poorly creates the impression of severe instability for the users who experience them. The nature of video conferencing/collaboration software means if 1 user's environment makes the experience unusable, the value for everyone who needs to collaborate with them is also seriously hampered.
That said, when we started dogfooding our own conferencing product it was partly because Slack consistently had issues dropping calls after 5-10m of group video. I'm kind of surprised to read such similar complaints 18 months+ on. Presumably it's harder to solve those problems at mass market global scales, we're pretty vertical specific.
Yes it must be very hard for one dude, but if anyone's in a position to make even just a decent version, it should be a billion dollar company who's core product is already pretty stable..
Don't forget the thousands/(millions) of companies who have enterprise contract for Office 365 and for which Teams comes for "free". Like the company I work for of hundreds of thousands of employees.
This is a good point. Office 365 seems to have a lot of free applications we don’t use (we tried teams 3 years ago...). They have a trello like thing and a file sharing like thing and a whole host of other stuff bundled in.
