Like he has spoken up about previously, there are teams' who won't give him the time of the day. But even going back to his junior days, he never really engaged in or did anything that was super egregious. All this guy does is have his own unique personality and way of thinking that doesn't quite fall in line with the cookie-cutter mold of what NHL really wants their players to be. Even in his time with the Isles when he wore #66, everyone including players, fans and media gave him shit over it. And he came out to explain that he was wearing it as a tribute to Mario because he was one of his childhood heroes. He wasn't putting on the jersey to disrespect him.
I think Josh Ho-Sang was to the Islanders what Nazem Kadri was to the Maple Leafs. And growing up through the minors after his draft, Kadri got absolutely shit on by the media and even a large chunk of the management. And he had never done anything wrong. He never whined, he never cried, he went down and played his butt off to wait for his next shot. In Kadri's case, the Leafs were terrible when it came to prospect depth and he was inevitably going to get his shot and he stuck it out through the non-sense to become an integral part of the rebuild. In JHS's case, the Isles were winning and there were toys shinier for the fans/media/management.
I've said it in my previous posts in this thread. Ho-Sang's flaw since he was young was that he was head and shoulders above his peer group. And that made him a selfish player who tended to go on solo rushes and hang on to pucks too long because he always thought he was the best option. And that was bound to piss off people as he grew older because this is a team game. I think he has slowly come around to realize that he needs to utilize his teammates to maximize his potential and secure a spot in the pro leagues. With the Isles, it was his inability to pass the puck on time that got him in trouble and subsequently benched. If he can limit his urge to try to be the best option and instead dish it early and often, he will eventually start being the recipient of more plays that run through him and naturally will get more scoring opportunities for himself too. Defensively, he has improved a ton and IMO he's a very competent defensive player who can slot into a top 6.
