I don't know why Tony chose him. Probably because of his interest in music and Tony thought Thomas was smart enough to pull it off.
I believe he has lost interest in ENTI. It's not something he worked for so he has no drive to see it succeed. His interest is in his ministry and his family.
He doesn't see us as real people who gave millions of dollars to see ENTI grow. He owes us nothing and he is doing nothing. In my opinion.
