The talk about national affiliation and worries of international implications are extremely premature imo. It is nearly impossible for a company to not have some suspicions of allowing a back door to one group or another. That said, the TCG is an open standard, allowing anyone to join. IMO you are not going to do much better than an open standard.
However, considering many are looking for any signs of sales, if we are in a position of worrying about eventual suspicions related to NSA affiliations, Militärischer Abschirmdienst affiliation (Military Counterintelligence Service of Germany) or the Ministry of State Security of China, than we are worrying at a higher level.
To me, it is the equivalent of worrying about driving a nice car when I have not eaten for a week. That's a nice little worry, but let's have lunch first.
