BitTorrent has never displayed any sign that they are in any way good at business. The only good thing to come out of bittorrent is the idea - even the best implementation of this idea was not done by bittorrent, but by utorrent. Till there are people will real business ideas at the top, the company will not be able to be a significant player.
"The idea" being the core protocol. I can't wait until you criticise Tim Berners-Lee for creating a poor web browser compared to Netscape. I agree on the business side though - it was always going to be an uphill struggle, and they seriously missed a trick by being beaten to market by Kontiki and seem to be struggling to find a decent business plan.
"The idea" is not the protocol. The protocol itself is nothing special, it's the idea that is special. I consciously decided not to praise the actual protocol, as there is nothing unusual about it.
