There has been so much loving praise of Microsoft on hn lately, while they would continue to use their same old tricks. A similar case is MS Teams, which won't enable audio or video on Firefox Linux without spoofing the ua as well.

This is especially insidious since so many companies are already locked into the MS ecosystem, users have no choice but to use edge or chrome and IT departments will start wondering why they would bother allowing the use of Firefox at all.
