Microsoft won’t care and doesn’t need to care until businesses actually switch away.
And I hope they do.

Microsoft Teams’ New “Chat with Anyone” Feature Exposes Users to Phishing and Malware Attacks
(cybersecuritynews.com)
Usually they get around this by offering controls for sysadmins at businesses to switch these sort of harebrained features off before they're rolled out.
This can all be disabled using the Entra b2b guest policy, from what I understand.
Very stupid to have this turn on by default though.
Had so much fun watching the so called teams update at work. It would break all sorts of things, it would sometimes be the old version, sometimes the new one, it would mess with logins and authentication... I think it gave our two it guys constant work for weeks!
Same experience here. I don't know how many times it told me I was using "classic" or "new" like they were flavours of coke.
They've been relaxing it for a while...
