As Chris Koss pointed out, the average person is going to assume that "The Bitcoin Foundation" consists of the people who are "in charge of" or "invented" Bitcoin:
non-Bitcoiners always ask, "So your company invented/operates Bitcoin?"
Only a tiny fraction of folks, the ones who are intelligent and thoughtful, are going to think "an institution financed by a donation or legacy to aid research..." The rest are going to think "So they invented/operate Bitcoin."
