I don't think they'll find out honestly, for the reason that Dribbles already pointed out.
However, if they did, they'd have some sympathy for Sasuke. Ino and Sakura would probably come to tears but I don't see them being to angry with the elders. If they did, Shikamaru would intervene and probably give feedback. I think even Sasuke has been coming to understand the Elders' decision thanks to Hashi and Itachi but that doesn't mean Sasuke will like it and neither will K11. I think acceptance is a better word here but it's hard to judge.
I do feel that Itachi should get a monument for his actions for Konoha. Kinda like Hiruzen had after he died but I doubt he'll get one to that scale simply cause Hiruzen is a Hokage and Itachi is not. He still deserves recognition but he preferred not to have it in order to not slander the Uchiha clan.
