FUD? That's not one I've seen before but I can guess what it means
Isn't the success of either approach going to depend on the environment? For some of the public trackers around that regularly have 100+ peers at a time, no-one understands how it works and everyone leaves a ton of torrents running I think you're right - having more connections open will give better overall download rates for your contribution.
But on a private tracker where people have to maintain ratios and seed back into the system I'm not sure it would work so well as people work to provide higher upload speeds on their end.
The protocol was designed to reward people who put more back into the swarm, but if nobody is really contributing much then you're better off playing their game and winning. Perhaps it's time to find a client that supports profiles to swap between the two approaches
