> All these are due to laws and regulations that are there to protect the big companies and don’t take into consideration users This feature is not due to laws and regulations. The user in this case is the presenter who clicks the button to enable screenshot protection on their meeting. This is Microsoft trying to deliver a feature their users want , not laws and regulations making them do something their users don’t…

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 prevents some accidental recording, which has value.

I haven’t had that experience when the same mechanisms were used to prevent screen sharing streaming video. I just fired up a linux vm, and hit play. If this thing actually breaks machines that don’t have a properly configured hdcp chain, it’ll create insane “this meeting is broken” debugging scenarios. Also, hdcp is trivially bypassed these days (if, for some reason a camera phone recording of the damning meeting is…

Old versions of it.

You have no idea. Infosec in my company would ask for this.

I think he meant "nobody with sense"

It's a mundane corporate feature request and quite reasonable and valid.

This isn't “we haven't tested your browser, if it breaks, that's on you”, this is “we don't specifically Trust™ the environment you're running your browser in, therefore fuck you.” “Web is supported” in this instance just means “the web, but only when mediated by google, microsoft or apple”, which is not the web as far as I'm concerned.

Hmmmm, I use Firefox on Linux to access Teams currently. Guess we'll see if that breaks.

Of course it's going to break. Remember when they built an actual Teams client for Linux? Remember how much Microsoft <3 Linux? Yeah, you're fucked buddy.

Oh well, I'll use something else then. Not worth getting upset about really.

Nothing that doesn't require a chain of Trust™ to the operating system will work, which is the point at which I start to get upset.

What's really going to happen is IT people will enforce this by default because good users aren't supposed to take screenshots, apparently.

I am a sysadmin and we will enable this. This is because many meetings discuss confidential or strictly confidential information that must not be leave the meeting. In-house, you would simply hand out papers that you collect before concluding the meeting. In Teams meeting it's not possible hence you block people from creating screenshots. This requirement comes from legal and compliance, and many other positions from…

The lede you're burying here is why a lot of this confidential info is so. Yes, protecting IP is important, but you're also primarily targeting whistle-blowers, abused employees, discriminated against employees, etc.

I mean, if HR says they won't make an accommodation because they think you're faking your disability than it's as if it never happened. Less transparency always benefits the immoral.

And this type of stuff does happen. A lot. We don't hear about it because:

1. Companies have gotten really good at just covering their tracks, like this.

2. It's a lot of effort to fight back and it's almost never worth it. You pretty much need baby killing material for someone to whistle blow. Lowly transgressions like discrimination aren't worth the effort.

I thought after Blizzard this would be a sort of wake up call.

You don't need to elaborate on mechanisms for bypassing because you're already imagining a threat actor that is out of scope. This is primarily about blocking accidental leaks by regular employees who were asked to not record but ignored it. This kind of reuse of content happens all the time in companies of any significant size and isn't entirely stopped by simple requests or watermarks. This tool gives companies one…

> regular employees who were asked to not record i think this should not be possible to be asked. For example, an employee might want to record to cover their own ass (e.g., if being asked to do some morally questional things, which the employee could record then use as protection against the company going back on their word). Having the ability to _control_ whether an employee can keep records independently of the c…

Trade secrets are a thing. Legal requirements are a thing as well. In some cases (think HIPAA) an employee recording something that they're shown can translate to significant legal liability for both themselves and the company.
