"I would put money that Google don;t want to do this and it's been forced on them by competitors who cannot compete on skill alone."
You're probably right: Google would certainly prefer if they could steal their competitors' IP, trade dress, and patents with impunity.
"Google had no choice."
Yeah, because the only other options were either to not steal their competitors' IP or license those things that their competitors were willing to license. And having a choice between not using their competitors' IP, stealing their competitors' IP, or licensing and paying money to use their competitors" IP, the Google Way is clear: steal and dare them to sue.
