It was, there was a ton of outcry because of their denial of such blatant AI art. One prominent MTG artist even ended their partnership with Wizards over the lie, which I think is ultimately what caused them to come out and admit it.

They also made a promise not to use AI art like two weeks ago, so now a lot of other artists are unsure if they want to continue their partnership with Wizards after being lied to. Make no mistake, if the artists weren’t willing to put their careers on the line to force this apology, Wizards would have just lied and moved on.
