I doubt it's real antagonism. Uryu is pretty clearly trying to play his part as Wandenreich Prince while simultaneously trying to protect Ichigo, which is why he tried to keep him away in 586. As for Ichigo, he doesn't know exactly why Uryu joined the Wandenreich, but he does know about his mother dying because of Yhwach and likely has his suspicions, but he also wants to save Uryu as well.
