I apologize in advance. And SPOILERS.
Kevin Feige told them to. Not in a mean way or anything, but, you know, he wants Howard the Duck in Endgame, he gets Howard the Duck in Endgame. It’s just how it works, man.

PS: Dare I hope that there’s a good Howard the Duck movie, somewhere in the multiverse?
If the Hulu animated series with Howard is any good, there may be hope.
I think I remember spotting him.
Of course, this isn’t his first appearance in the MCU, as he also had a brief cameo in Guardians of the Galaxy.
