Certainly, an interesting, half-technical angle to consider when
thinking of doing something like this.
Folk that are pushing out /24's with the expectation of the rest of the
Internet steering traffic a certain way toward them, being surprised by
the "brokenness" that can be created due to the decision to override
"longest match" in favour of spending less cash.
Who has the right to complain the least, or the most, in such a situation?
A: "So why don't you have a bigger router that can take our /24?"
B: "Well, we don't have the money to afford taking a /24."
