Update Teams using the latest Electron/Chromium version
The current version of Electron used to compile Teams is VERY out of date and is using Chromium v69, while the production version of Electron currently is using v83.
Using older Chromium versions in environments that have security audits can cause problems since it has the potential to flag CVE's that are unpatched in older Chromium versions. Not to mention, newer versions have various bug fixes and performance enhancements.
"Electron to React" these are different things, your link seems to talk about moving from Angular to React (put only a part of it). There is nothing stopping you from running something made with React in Electron. There is something called React native that could possibly be an alternative to Electron, not sure there are any plans for that though.
I think they're moving from Electron to React, so I don't know if that would affect this request.
Teams is 75% through its life-span. Unlikely teams will be moved to a new platform.
The magic escape clause to avoid having any legacy software cost problems.
I knew MS was using a woefully unoptimized version of ElectronJS, but holy moly I didn't realize they were asking for the client side desktop app to be exploited so badly.
Really hope they switch to something other than Electron, or at the very least, follow Discord & Slack's steps by heavily customizing a newer version of Electron so Teams doesn't run like hot garbage on my i7-4790K 32GB memory system.
Though I wouldn't hold my breath... they've been "working on it" over the last 4 years.
How about bailing on electron so we can have a decent freaking windows installer for corporate systems?
