Yes it is an explanation why.
Your question: Why is/should this be acceptable.
My answer: These are school issued machines, and like all machines issued by a 3rd party for use under their supervision, they come with monitoring software.
It is acceptable because it is the schools property and they can do as they wish with it. Everyone else is free to not use those machines.
This is not a hard thing to grasp.
But since you are just being combative we are done here.
Offer a real conversation to others instead of being combative and maybe you will have better results with people in the future.
I never once stated I was "pro company". Another tip, free of charge, don't put words in peoples mouths. Makes your already faulty argument moot.
Yes.
No one is forced to use a laptop. Libraries exist with free internet access and computer.
Yes. If you do not think it is I can only assume you weren't a child when the internet became a thing. I was "monitored" on school computers in the 90's and this is no different.
Now are you actually going to participate in good faith or should I simply block you?
