and bang goes Windows, and all the resale value.

Legally you can't sell on Windows anyway

Thats not correct. Legally you can sell on anything you paid for.

Fraid so.

Legally (morally is a different matter) you haven't bought it merely
bought a license to use it.

Just because someone claims that doesnt make it legally gospel.
