Google does not have the power over Verizon like Apple does, plain and simple. They allowed Verizon to have control over the Nexus and that's what we get. We all know the Nexus is supposed to be a Google experience phone, but the Verizon version is far from it, and this has been fact since before it was released after all the delays. On to your second point, unfortunately, we at DF make up a very very small percentage of the smartphone community, though I'm sure you've spread the word to others.
So yes, many of us agree with what you're petitioning for, but all the past efforts have been futile. I signed your petition in hopes of maybe something happening, but my hopes aren't high at all. I applaud your effort into fighting for the small percentage who demand complete control of their device. Said this over and over again, Verizon has botched the Nexus since before it released and it won't get better anytime soon. So again, you want the Nexus experience? Turn to the devs. It's one of the main reasons why this phone is still around and it's the main reason why we love the Nexus, at least most of us here at DF. Rooting, ROMing, customizing, it's all part of the addiction of the "Nexus".
