That is absolutely not what the author is saying here, just that users should have the ability to install their own software on their own hardware, and that locked bootloaders and the like should not be allowed.
Also I don't want others to be able to use my phone after stealing it.. here FRP lock helps me but in order for it to work it must also limit how I can use the phone.
I wish we stopped falling for this technical trap and finally focus on the substance - hardware/software companies get away with anti-user features that run on the user's device. This shouldn't be allowed.
I don't need an unlocked bootloader, I just don't want the preinstalled Google spyware. Google should not be allowed to hold my device hostage like this.
