Yes, you're right, even the NBA technically forbids teams from interfering with their players participation in international compe ions -but I remember some stuff about Cuban and Dirk 5/6 years ago-.
Well...In RC we trust
Yeah, even any kind of suggestion is forbidden, if I remember the CBA correctly. Obviously, you always know these people talk.

I personally think he has nothing left to prove there. He does feel incredibly grateful to be part of both great, historical teams (Spurs and the ARG NT), and I know he thoroughly enjoys playing with those guys.

But I think the fact it was a long season and his new kid being so young, I think he might just not go. We'll see. I prefer if he gets some rest. Like it or not, the Spurs have also had 2 deep runs into the NBA Finals. It might be his last season in the NBA, makes sense to rest and try to retire on top.
