Sometimes I think "oh! But Tony went to visit them in The Raft" but then I remember he only did that to get information on where Steve and Bucky were.
In that one short visit he:
saw Wanda in a straight jacket and fucking collar
and did nothing. And proceeded to still do nothing even after he left The Raft.
Outed Clint's family to Ross, which not only is a massive security risk for Laura and her children, but also a major betrayal of Clint's trust. Not to mention the way he mentions them, which is to guilt trip Clint.
Oh and he also did not show any remorse for shooting Sam point blank in the chest, after getting Vision to try to shoot him down in the sky :) when he was not wearing armour :) Unlike Rhodey, who unfortunately got hit. Tony Stark does not even inquire about any of that.
