My comment wasn't meant to compare it to anything else. Their nice words just don't convince me on a technical level and I'm surprised that so many people here appear to fully trust them.
If their phones were perfectly secure there would be no debate if they are willing unlock the phone for any agency or not. It would simply not be possible and there would exist no security company that is able to do so.

Total security is not possible, not at least by a long shot.
Although, I understand your concern about why people trust these companies. While I don't know the answer just yet, I think one reason is that most these companies are located in Western countries where "rule of law" is considered extremely crucial. Openness about balance-sheets, government policies, and privacy are - to the best of my knowledge - critical in the US.
