Exactly, this is how Microsoft operates. This time they gave an excuse they still allow plenty of other browsers (with the same engine). Google loves it, because it hurts Firefox and they can say they are not responsible for 3rd parties blocking sites.
I wouldn't be surprised if this is coordinated based on lessons learned with IE.
people using user agent switcher so they can use bullshit like teams probably introduces errors into the statistics so microsoft can claim most users use chromium anyway.
Should be better with v2, normally. V1 uses electron and an old angular version which both were slow as fuck and used a shit ton of resources. I also think electron doesnt support the arm platform yet? (citation needed).
Anyway, v2 uses react and a better webapp engine to run as an app so it should be faster. Not surprised if it still ran as shit though haha
And electron does support ARM, or at least it runs on M1 Macbooks. We use Teams extensively in our org, and we have a mix of M1 and Intel Macs, and we also have an electron app we maintain (and our QA uses an M1 Mac for testing).
