The Windows licenses only matter when buying a Windows DVD without computer, they barely reflect on the whole computer price.

In fact in some stores that sell computers with FreeDos or Linux, the models tend to be more expensive than those with Windows.

ChromeOS by being a browser based OS, means all applications run in someone else's computer, no way to turn tracking off other than not using ChromeOS at all.

Likewise, what each Android model allows to turn off and what gets tracked depends pretty much on how each OEM has customized their Android version.
