So what? "Not for sale" means that those devices haven't been made for commercial use. It means that Nokia never planned to sell those devices but instead gave them to developers etc. But Nokia is practically dead when it comes to smartphones (I know about HMD but it's different thing and not to be compared former Nokia business). "Not for sale" doesn't mean that owner of the device can't give or sell it away. Nokia is not going to collect them back. So no need for outrage every time somebody decides to sell his/her developer device.
