Everyone knows OS and software, browsers, etc all use way more RAM than they used to, and arguably more than they rightfully should. Bloatware, etc.
I saw something recently that alleged MS puts a lot of shit into PCs that say they are doing one thing but are really doing another.
It would be wild if they are basically using the PCs of the world to do something like crunch numbers, mine bitcoin, etc. Oh, hey, this guy has 12 gigs of ram and is only "using" 4, that's 8 for us to sap.
Regardless of what they're doing now, the end goal is to control everything.
"You will own nothing and be happy." (They don't actually care about the happiness though.)
There will be shutoff switches and other control mechanisms in everything; cars, computers, fridges, toasters, and your very electricity. If things progress far enough...you. You will have a killswitch. That's what they want.
Yes, this is my bigger concern.
If they get their way (not just Microsoft; all of big tech. Apple has been doing this as much as possible since the iPhone), you will not be able to run any software that they don't allow. You will not be able to develop your own software without a proper license controlled by whoever built your OS and/or hardware.
I'm assuming future OS ToS will include their right to use your unused computer resources for their own processing needs.
