Show me those rainbows, but I think we might be playing chicken-little a bit too soon.
Now, as a huge Linux user, I will always recommend weaning yourself off Windows whenever possible, but I think people are making a bigger deal out of this that it is.
From what I have read, and from the excellent (IMO) summary Mutahar did in his last video, it appears that there are some limitations to this that people might be overlooking:
1. This feature will only be available on very specific Microsoft tablets and laptops that are running a very specific ARM processor. It's not something that should affect any current Intel/AMD/etc hardware in already existing PCs/laptops/tablets.
2. This is going to be included only in the versions of Windows 11 specific to the hardware referenced in point 1. This will NOT be included in a future Win 11 update. (At least for now.)
3. This appears to be something that you can "turn off", as well as filter what gets screencapped or saved. It will probably be "on" by default, but turning it off appears to be an option.
Now, without question, the fact that this feature is being implemented at all is fucked up like a football bat, and it's mere presence will prevent these devices from passing many of the strict security policies most corporate IT have currently implemented (SOC2/GDPR/etc), but it is easily avoidable by NOT allowing the use of those devices on corporate systems.
As far as I can tell, this is the equivalent of putting all of your homes valuables, jewelry, art, money, etc. in a easy to carry box right inside the front door of your home. Sure, you might have four dead-bolt locks on your front door, BUT should someone successfully break in, they don't need to rummage all through your house looking for loot. You've placed it all in one convenient, easy to locate place where they can quickly pick it up and be on their way.
