Most of the big box bookstores carry like two cases full of Marvel and DC stuff, we already see why that isn't a problem in the article and a case full of boutique imprint stuff that are all actually produced by bigger publishers, read, they didn't get those from Diamond either.
I'm sure the single issues they ordered amounted to an account about our size. I doubt very seriously that it will crush Diamond, but who knows how bad off Geppi is, it could. If losing one mid level account is going to spell the end of comics, we are doomed anyhow.
