Considering how many times they claimed, that this game wasn't forced on them and they indeed wanted to make it, I'm inclined to believe, that we're indeed trying too hard to take the blame off Rocksteady themselves.
I mean, there's always a chance, that they wanted to make as much money as possible with live service model (though after Avengers it was obvious, that this plan was doomed) + they chose to make Suicide Squad, because they were sick of superhero games and had no interest in making game about Superman or any other JL member, or even about the entire team.
