Google and their partners could have taken the high road and created their own take on what a touch screen phone OS is, but instead they took the low road and did a wholesale look and feel copy and paste job of iOS to get scale.
Copying look and feel isn't actual wrongdoing, but it's certainly not the high road.
Now Apple is taking the low road and trying to smack the fuck down Google legally, instead of taking the high road and competing on its own merits.
Both companies have taken the low road, and both companies are culpable here- no one comes out looking good in this story.
