I really don't get dude's problem. They trying to build hype for the fight and they know McGregor's shyt in boxing so they pull pics like that to build hype. I mean if you getting paid

Then get paid.
Theyre doing it at his expense
Paulie is a respected pro boxer. Regardless of all the shyt he gets about pillow soft hands, dude was a winner, champion, and a very intelligent boxing commentator. He knows his shyt
So for Conartist Mcgreggor to insinuate that Paulie got knocked down is cheap and makes Paulie look bad (which is what he intended to do the entire time).
They basically set Paulie up to look bad like Mcgreggor was beating the shyt out of a out of shape, retired professional when that wasn't the truth.
Conor couldve released pics of him with the other sparring partners but didn't. Paulie is a public figure who was going to be asked a ton of questions by regular media and clowned on social media. Conors camp knew that.
Paulie was actually trying to build him up after the first set of pics but the "knockdown" was the last straw especially since it was a push (referee was by Conor, if Paulie was hurt he would be by him instead)
