Google will brick Google Glasses if owners resell or loan them out

I understand that Google wants to make up as much revenues as possible from their pioneering glasses. They have spent a huge resources to develop the glasses so I don't see anything bad in wanting to turn cost in to profit.

However everything should have its value. Well, Google Glasses, it's a highly inovative solution so let's impose "non-standard" conditions. In this light, in case of the glasses resell without a permit, OK, let's deactivate it. Though this measure is still very questionable. But deactivating just due to loaning ... it's completely off and too harsh. Here Google overshot.

I have mixed feelings about Google. Although they do have some very innovative products, they seem to be turning more and more into a "Big-Brother" type of company.
 
I have to say that I am finding myself not fully trusting them anymore.
