Well, Tor appears to me partial counterexample to "the theory of many

Even if the chip is community designed, do you really know what "the
community is?". Who audited it?

Also, the implementation must be exactly what is designed.

Can't find reference ATM, but pretty sure I read that faulty NAND gates
can compromise a lot of things (crypto too), while the metal appears to 
work as designed.

How do you verify a chip is what is claimed to be? Maybe peel it, take
snapshots and then reverse engineer the wiring/gates and compare to the
source (VHDL?) ?

As for phones, I don't keep anything of importance on them and consider
them compromised. Might not work for you.
