The version numbers are lying. The Linux version is missing important features, like seeing more than 4 participants at the same time, or blurring the background. Also, for some reason it is often not possible to see the camera picture of participants when they start screen sharing (if they are using the Linux version, that is).

I don't know about the number of participants, luckily I've never been in a mammoth call. As for the background blur, it may be related to a missing feature in Electron. I seem to remember that another conferencing app (might have been zoom, not sure) didn't support this while running on Chrome/Linux, so I figure it's related. To me, the main missing feature on Linux is the "native notifications" feature (as opposed…

I don't think it's a limitation with electron on Linux. One time I joined a meeting with an external org, and probably due to some bug in teams I suddenly got more features like e.g. background blur. The next meeting a couple of hours later the features were gone again.

> a rash of anti-zoom propaganda that I'm almost certain was driven by Microsoft Zoom had and continues to have a significant developer presence in China. Those individuals are subject to CCP coercion. There was also a time when they routed American calls through the mainland [1]. That has been fixed. But it remains excessive to cast all past criticism of Zoom as Microsoft's work. [1] https://techcrunch.com/2020/04/0…

I remember when they stories came out they were released in a suspiciously coordinated way. Once one died off another was released to build up momentum again and keep the idea humming in the public consciousness. I figured that it was done by a big party that had a trusted relationship with tech journalists because they bigged up vulnerabilities that were relatively minor to journalists who didnt seem to be aware of…

No conspiracy required, just change "party" to "parties" and "someone" to plural "people".

Zoom went from interesting tool to de facto worldwide standard in about two months. I'm pretty sure that in the offices of Microsoft, webex, goto meeting etc there was a collective WTF from leadership and people were instructed to find weaknesses. It doesn't follow that there was collusion or an evil conspiracy.

As an anecdote I know of a certain top-100 company that ditched their in-house competitor to Teams because MS made them a sweeter O365 deal. For a time management forced them to use Teams even though they were still developing AND licensing the in-house competitor to other companies. MS is really aggressive with Teams marketing (specially for large bureaucratic enterprise) and I could totally see them doing what you…

Discounting a different product to kill competition? I'm no antitrust expert, but isn't that illegal? If not, it should be.

No, it would be abuse of dominant position; it is illegal only if you are in a dominant position to begin with.

What I know is that almost every company I have to deal with use Office 365, so they use Teams, and almost every school in my area use Google Suite (BigG got quite good at being the new Microsoft), so they use Google Meet. Almost no one use Zoom anymore simply becase it's not integrated with anything.

Zoom integrates with a number of things pretty well (e.g. "Add Zoom to Meeting" button in Outlook create appointment interface) but it's not bundled with systems organizations already have, like O365 and Google Workspace (or whatever they're calling it these days). I'm sure Google Meet is used in most of K-12, I don't know about higher ed. The university I work for licensed Zoom pre-pandemic because it was superior t…

Yeah, bundled is a more correct word, that's what I meant. AFAIK, Teams doesn't need an account, but I have used it only in a business context, so I'm not sure.
