There is also spyware running on them. They literally spy on what you're watching and send the info home, and the data gets sold to market to you. No thanks.
Edit.
They also connect to unprotected wifi networks to send data without your permission.
And in the case of Toshiba at least, use their own hardcoded DNS which doesn't honour the one handed up by local DHCP or even the one configured in the advanced settings where you can manually configure the DNS!
