Bullshit. Currently there are millions of children who are obligated to use Teams for their publicly funded education.

And thinking these huge metrics get changed by selling black hat exploits to what? Teach Microsoft a lesson? While harming an already vulnerable population (not just children are obligated to use Teams). As if the long term goal of educating "unwitting" users is advanced at all by blackhat behaviour.

Microsoft has had a serious reputation for being a serious security risk for the 30 or so years I've been in IT. It's one of the oldest jokes in the industry. People and the world in general clearly do not work the way you apparently think they do.

Zoom still has a ton of users, and every single thing they make or do is a serious security risk (or has been in the past, evidencing a distinct lack of secure development culture).

Windows XP is still seen in the wild.
