To borrow pro-wrestling terminology, I have considered at times that the Guntfight may have all been a "worked shoot"; there was genuine beef (May breaking up with Digi, along with her alleged infidelity with Gunt) and fists were meant to connect, but perhaps only with pulled punches (maybe only MintSalad couldn't control her retard strength in her straights, thus opening up Gunt's face, causing him to bleed), but perhaps everyone, including Gunt himself, was in on it, with Gunt's constant bringing up of Dick only to be censored by Digi, suggesting that it may have all been indeed a "pitch" for Dick's patronage, as you have put it. Really, why would Riley have any beef with Gunt to begin with, unless it was fake? Wiggers love drama, even if it's the fake and gay kind they've created.
May leaving her belongings behind in Digi's house (along with the alleged theft of Digi's Nintendo Switch by May's Dad) may have been the pretence to create such fake internet drama.
Then again, Riley refusing to appear on The Dick Show to shoot a promo on Gunt would kill any "work".
It has also been almost three months since the fight, with most people probably having completely forgotten it (or at least lose interest in it) by now. Even this thread had a resurgence of interest when that video dropped, but as the Ygg Crew collectively have no idea how to create entertaining content (with the Guntfight opportunity having been practically given to them), it has lead to this site also losing interest in Digi all over again.
Come to think of it, why didn't Dick invite Riley as the main guest instead of Ralph? The former is his employee, so he will say anything Dick wants (to drum up drama), while the latter is a self-promoting braggard loose cannon.
