They've already been doing this with Teams. Their native Linux client has less features, like screen blurring, or being able to view more than 4 users at a time. Thankfully you can get around this by using the web version, but who knows how long it will be until they do some user-agent shenanigans to mess with you again.
Their native linux client is an outdated version of their web client using a outdated version of electron (I think it was electron), i.e. it's not native do not use it, use the browser.
