Google can't be said to be "against root," really. We continually see phones released with bootloader unlock allowed natively. I mean, all of Google's own phones - Pixels, Nexuses (Nexi?) - have permitted oem unlocking since basically ever (Ok, not sure about the Galaxy Nexus). All of the OnePlus phones have permitted it (save the new T-mobile 6t). It's mostly the CARRIERS
who forbid it because they have a vested interest in making sure you can't take your phone to another network. Oh...and Samsung.
Full disk encryption is about user privacy, and I can't stress enough how important it is, but it's a separate argument.
I understand the underlying motivation for employing a warning screen like this. For someone who doesn't understand all this stuff, having a blatant warning is beneficial because they will know their device has been tampered with. On the other hand, I'm fully aware of the risks involved with unlocking, rooting, etc. I choose to do it because I'm using it to enhance the functionality and security of the phone for my very specific use-cases. That said, if I could mitigate one additional threat by not broadcasting to everyone that my bootloader is unlocked, maybe the attacker moves on to an easier target.
Whether you like it or not isn't really important to my motivation for asking these questions.
