It's fair to say that the conclusions from the TSB are based on circumstantial evidence. But AFAIK the TSB tends to be thorough and methodical, and doesn't serve any political agenda. So it's probably pretty good circumstantial evidence -- which I grant isn't the same as positive proof.
Here are a few more articles worth reading (some from a while ago) for anyone who is interested:

(And as I recall, it's pretty impressive when those big props wind up.) Probably not a big margin in the business, and it's probably not that easy to turn down a fare. These guys are good fliers, but aren't making the big money; and there's no airport security establishment to screen passengers. It's the classic cabbie's dilemma, except at 500 ft. you can't hit the brakes and pull over. Very sad that this pilot lost his life over a 6.5 minute fare.
P.S., Apologies, Mods, I quoted too much in the OP.
