Easily circumvented: Use two monitors, one positioned out of view. Use a teleprompter mirror with a camera behind the mirror. Use a video capture device, record on a separate computer. I'm sure there's sneakier ways to perform this...

Your “easy” circumvention requires a second monitor, a teleprompter mirror, a camera, a separate computer and a video capture device. Remember, most people who use Teams don't work in tech. And for them, that’s not “easy”. Barely any normal people have that kind of equipment just lying around, along with the expertise and desire to set all that up, ready for a teams meeting.

For every 100 people who might decide to take a screenshot during a teams meeting, I doubt there’s 1 person who has all that equipment set up and ready to go. You don’t need to make something 100% effective to get a benefit from doing so.

These comments are akin to pointing out that the privacy door on a public bathroom stall can easily be bypassed by looking over the top of the stall walls or underneath the gap between the ground and the bottom of the wall. In their rush to be clever, they instead demonstrate that the poster completely missed the point.

but it is so easy to circumvent, even my teenage daughter, who doesn't have an interest in tech, knows what a capture card is and knows what an hdmi splitter is: she hasn't even entered the workforce yet and she already has all the ingredients needed to circumvent a software block on screenshots

:-D

You turn your camera off for 10 seconds, take the photo and turn the camera back on. No-one would notice a thing

If you wanted video just have the device positioned outside the field of view. Laptop cameras fov is very narrow.

Sibling comment's definition of "easily" varies materially from my own!
