We don't know if he's still involved with Apple. Only source of his ownership is an old media article, he never reached the threshold of ownership to file publicly which means he also could have exited the position at any time.
Good point. But curious why did he decide to come out after being radio silent for quite long time and get involved in Apple's war specialy given that he is now CEO of a public traded company. Trying to capitalize by siding with common people? His personal opinion? Who knows!
