I think you "got it". Some other people argue about disadvantage of forcing people to trust google or nothing. They don't realize that other than google, there can be any company that produces their own computer hardware. There are choices.

The bottom line is that the absolute trusted hardware is a hardware you build with your own hands, including etching and doping your own transistors. All other choices are a compromise. There is no such thing as having a compromise and having an absolute control at the same time.
