Is Android-based Google Glass being "sold" or "licensed" or "leased"?

What are the implications for the free/libre/open app developer community?

"Glass Terms of Sale: You may only use the Device in accordance with the instructions that come with it, including instructions that may be available on line. ... Google reserves the right to make changes to these Terms or the applicable Device Specific Addendum from time to time, and any such changes will take effect immediately. ... you may not resell, loan, transfer, or give your Device to any other person"
