Pat Spillane says he was angry after finding out that Dublin had broken the GAA's Covid-19 regulations.
Dessie Farrell was handed a 12-week ban after at least nine of his players were pictured partaking in a training session.
Spillane was shocked when he heard the news initially, but was then angry at the All-Ireland champions for holding the session less than 12 hours after the Government had introduced a new road map.
Speaking on the RTÉ GAA podcast, he said: "When I heard the Dubs were breaking the rules, I was stunned. I was shocked, I was amazed.
"With the Dubs, everything is managed. It's all about protecting the brand. It’s all about controlling the narrative. No-one knows what is happening inside of the camp.
"It’s a bit like the brightest boy in the class suddenly being caught cheating, or you suddenly realise that the local parish priest has a wife and family in the next county.
"You look up to the Dubs as these are your role models.
"After being shocked, I was angry.
"This particular training session, and it mightn't have been the first, took place less than 12 hours after the Government had introduced a new road map and at last, announced that on 19 April, inter-county training could start.
"Anecdotally, you know a lot of counties are at it. In Ireland, when it comes to cute hoorism, and whataboutery, we’re world champions. Our get-out-of-jail card is, 'well, everyone else is doing it so why can’t we do it’.
"It was wrong. It was bad, it broke the laws of the country and GAA regulations.
"The GAA season hasn’t started yet, inter-county training hasn't started yet, but four of our top managers are suspended and justifiably so."
But Spillane doesn't think the episode will hamper Dublin on the field.
He added: "In one sense, they were wrong, wrong, wrong. In another sense, there is no danger with Covid transmission outdoors. It was much-a-do about nothing.
"It won't affect them as footballers or a team, but the brand has been damaged to a certain extent."
