I mean, it matters to the guys running that site because it directly fucks their job/income. I know MMA photographer Esther Lin also got escorted out because she's with that team so she missed out on shots during the main event.
I'm sure whoever is leaking info to Helwani is gonna keep doing it, but this was just Dana getting butthurt and flipping the table over.
I mean from the UFC perspective
Did Dana promise ESPN an exclusive or something on monday?
Then why deny it at all?
All that says is somebody in the UFC leaked it. If it was from the WWE side it probably would have come from Dave and he has held info if a party wants to debut it a specific way(such as when the WWE hired Mauro Ranello he knew for weeks because he is friends with Frank Shamrock).
