I think Microsoft’s planned recall feature where they screenshot everything you do so that it can be analysed by AI isn’t as bad as everyone makes it sound. It’s only bad because Windows is closed source and nobody can verify if what they say is true.
But if Microsoft aren’t lying and none of the data ever leaves your PC (which is supported by the fact that you need a pretty beefy machine to use it) then it is one of the more privacy friendly shit they’ve done recently. And I think they were fully aware that they could only sell “thing that records everything you do” if they could convince people that it doesn’t share that data. Guess they failed.
If it were open source I might even think about using it myself. If the hardware and subsequently power requirements weren’t so absurdly high.
One small bug in implementation can make it a juicy attack vector. Sure you can configure it to give more privacy, but how many users will do such configuration? Many casual user didn’t even bother changing their user/computer name (how many times have you seen the user named “user”, “asus”, or any other default?)
