"Google has succeeded in [...] created a captive environment "
Well duh, that's what you get when use Google's API everywhere.
Apparently, someone should tell Getty that it is possible, as a poster above has already said, to control web spider acces to one's site. I remember 15 years ago having found out that a page on my own personal website was being displayed somewhere else without any credits to me and without copying the entire frame, just the data they wanted, so that everyone would think it was their own page. I quickly found out how to force them to display my entire page, with my header and logo.
If I can do that all by my lonesome, I do believe a company, let alone Getty, would have the means to do something about Google's image copying.
