Not so much... If you buy a Verizon Pixel it will be locked until an exploit is found. If you buy a T-Mobile Pixel you will still have the same Network Unlock crap that all T-Mobile phones have.Pixel phones are always good because theres no hoops to go around to unlock it and root. Also to get root use this thread for in2017(tmobile) model: https://forum.xda-developers.com/t/guide-android-11-how-to-root-t-mobile-op8-5g.4228303/
For verizon use this thread: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4191723/
If you buy straight from Google, yes, its full unlockable from the factory.
