There was a PA school district back around 2009 that issued laptops to students preloaded with spyware that let school staff watch students through the webcam, while the students were at home and not doing schoolwork. Neither the students or parents were informed of this. IIRC the FBI got involved but nobody actually got in any real trouble, I'm not even sure they were fired.
I wish things weren't this way. You could maybe use Wireshark and black hole anything the spyware tries to connect to at the router, or maybe add the addresses to the hosts file on the machine itself (not sure if ChromeOS lets you do this).
