One does not commute "from" a place to itself. You're trying to backpedal, but your chain is tangled in the English language's entrails.
It also makes no logical sense, as there would be no reason to mention where they commute from unless you thought it was of some significance, in which case you would want to be clear on where they are commuting from. Or are you now trying to insinuate that every engineer in the Bay Area (now that you've reversed your position and agreed the term is not limited to the peninsula), including Cupertino, is mediocre by virtue of being there, rather than only those engineers from the immediate San Francisco area?
At the end of the day, the engineers that I personally know who contract at Apple are competent but not great. They happen to commute. The two are not related. There is no insinuation in the original post that all engineers who commute are mediocre.
I am however insinuating that the culture at Apple may have changed, which allows merely competent engineers to be hired in the first place, while great engineers like Bertand Serlet leave the company, to the detriment of OS X.
