Lack of professionalism maybe. However, the fact that there was no official action taken means there was no censorship. As far as why Disney initially suspended Kimmel:
"We made the decision to suspend production on the show to avoid further inflaming a tense situation at an emotional moment for our country. It is a decision we made because we felt some of the comments were ill-timed and thus insensitive.” - https://apnews.com/article/jimmy-kimmel-show-suspended-charlie-kirk-ae43c600bd0f2a4c7d3c12077e91b211
And as far as why some other affiliates kept him off the air longer:
“We made a decision last week to preempt ‘Jimmy Kimmel Live!’ following what ABC referred to as Mr. Kimmel’s ‘ill-timed and insensitive’ comments at a critical time in our national discourse,” Nexstar said Tuesday in a statement.
“We stand by that decision pending assurance that all parties are committed to fostering an environment of respectful, constructive dialogue in the markets we serve,” Nexstar said.
In neither case was censorship or pressure from Trump or the FCC mentioned as a reason.
