With both whatever-apple-is-doing and Android’s whatever-it-is-called-that-prevent-factory-reset when you don’t have access to the account on the device, I don’t see how people still buy “shady” phones and tablets.
Last time I borrowed a relative’s phone to run an experiment, I had to contact them to “unlock” the phone after a factory reset before being able to do anything because I didn’t remove the account before. Unless people go out of their way to make their phone “stealable”, that is.
You can factory reset it, but not really. On first boot, the phone requires a network connection; you can’t skip setting up wifi if there is no cellular internet available. And it will ask you to authenticate the google account it expect before even starting the “real” setup process. As a matter of fact, once you authenticate with google, it does start again, ask again for wifi and will not have the account setup at all, as you would expect after a factory reset.
So, while you can “factory reset”, the phone still needs the previously registered google account to start. There’s probably some phone that gives more leniency, but I was not able to circumvent that using adb (the device being locked, and impossible to unlock without accessing the menu, impossible to access without starting in the first place…)

I mean, if you can factory reset a phone to strip the need for authentication, that seems like kind of a bad thing, no?

I have seen several tutorials to skip this step on xiaomi phones through fastboot.
If the phone had is bootloader unlocked, sure. Otherwise, it won’t accept the commands. My mistake was on a Xiaomi Mi A2.
The people that designed this feature are not that oblivious.
