But back the the original premise. If say, Linux is being distributed both from a central web site, and via P2P: 1) Central web site. All but the one ISP with the web site will have the traffic going over peering or worse transit, and will often be carrying them thousands of miles from the central point. 2) P2P. Has a good chance at least some seeders will be on the same network, avoiding peering and transits for some fraction of the traffic. Has a good chance the seeders are closer to the user than the web site, perhaps even on the same cable segment.
In the UK at least, option 1) is financially more favourable for ISPs, since the data flow is
vendor -> transit -> last mile -> end user,
end user -> last mile -> last mile -> end user.
The last mile is where all the costs are.
