I've read both the blog post and the linked article. Can you provide specific quotes for the claims? Because the only thing that came close which I saw in either the post or the link was a graph of a different connection which isn't fully saturated, but has very little head room, certainly not enough to handle the spillage that L3 is dealing with. There's a mention of capacity upgrades in the works for that connection, but no specific numbers; it's not clear that the upgraded connection will be large enough to take on the lost packets from L3. And I didn't see anything in there about L3 pushing other providers out of the way.

So like I said; can you provide sources for those claims? Because you also thought the bakery analogy was a good idea, so I'd like to read your primary sources instead of trying to explain myself to you further.
