A Verizon spokesperson has reached out to Ars with the following corrections about its version of the Pixel:
"First and foremost, all operating system and security updates to the Pixel devices will happen in partnership with Google. In other words, when Google releases an update, Verizon phones will receive the same update at the same time (much like iOS updates). Verizon will not stand in the way of any major updates and users will get all updates at the same time as Google.
Also, the Verizon version of the Google Pixel is carrier unlocked, so you can use it where ever you like. Finally, we have three apps pre-installed on the phone Go90, My Verizon (which is your account management tool) and Verizon Messages (your messaging app). As you noted, all three can easily be uninstalled by the user."
Google told 9to5Google that "system updates will be managed by Verizon for Verizon models," which in the past this has meant slower, delayed updates. Verizon seems to be changing their update strategy for the Pixels, and now promises to "not stand in the way of any major updates." We've reached out to Google for comment and clarification.

Should be a relief to the folks who had to/wanted to order from Verizon.
