Good summary. It's best to think of controls like this as guardrails. They are mostly "safety" features rather than hard-core security features. They help honest people to avoid potentially dangerous mistakes.

Guardrails that break support for devices that aren't owned by the equipment manufacturer, yeah, about that…

It doesn't do anything of the sort. It will work on PCs, Web, Android and iOS - everything with a supported client.

Not sure what "support" you expect for unsupported clients.

> Some people might want it, but it doesn’t actually work Why do you think they can't prevent on-device screenshots/screen recording can't be prevented when you control the entire stack?

They can't control the entire stack because of the analogue hole

Which doesn’t matter at all.

Yes. Edit: But yeah, nothing to say why it can't work. So, yeah.

But MS doesn’t control the whole stack there.

Doesn’t matter. I don’t know why you think stating random things matters.

What about a camera? These aren't the use cases that really matters. What matters is the common case, and it's not about deterring honest folks. Honest folks aren't recording. This is really a lesson in security blind spots. The number of people that are trying to "get around this" assuming that's the issue. Edit: I'll make it simple. It will work because honest people aren't trying to get around it. But, they could…

> Honest folks aren't recording. Honest folks who want to be able to cover their ass later on are. Honest folks who are working for dishonest people and are planning to be a whistleblower are. Honest folks who have Recall on are. Possibly against their will if they haven't found out how to turn it off, or it's a work machine where they're not allowed to do so. Maybe they're not if Microsoft actually has enough interd…

And in all those cases they still have a solution, a better solution. Seriously, think.

Will it though? If I join from Linux using Ferdium or any other browser what will prevent me from using any screenshooter? Or will web be considered an unsupported platform?

But it’s literally the dumbest feature ever. There’s absolutely nothing preventing a user from pulling out their phone and taking a picture of any slide they want. Or having a camera recording the whole session out of view of their webcam. It is security theater at its peak.

It's not pure security theater, there are a few clear gains for those who care about such things: * Naive screencaps are much less traceable to the leaker than a naive photo is. Yes, someone can strip out EXIF data, but we've seen over and over again that they generally don't. And even without EXIF a naive framing on the photo is more likely to expose information about the location or identity of the person who took…

What's the endgame here? Mandatory HDCP monitors for meetings? HDCP for absolutely every application?

The article says web is supported. Whether that means all browsers or just some, no idea.

That's frustrating. Can you can still, if you have Android, use the text capture feature built in that reads text from bitmaps? I use that everyday for sites and apps that don't allow copy paste.

This was part of a larger security policy change that also dropped support for my phone manufacturer so I couldn't say.

Perhaps a little less snark would be appropriate if you don't know what other people are talking about.
