With that clip of Trotz, you are making my point for me. It is clear that Trotz was initially encouraged by Ho-Sang's play a couple years ago and had no ill-will towards him. JHS had a clean slate.
I am not a fan of MDC so I probably would have kept JHS over MDC, but I can understand the Isles thought process. MDC didn't get much ice time when other payers were healthy at the start of the season, they wanted JHS to go down and work on a few things in Bridgeport and they correctly guessed that they could pass him through waivers.
Wahlstrom and Holmstrom were also sent down around the same time while Bellows was sent down a week earlier. The Isles sent down multiple prospects with talent, it wasn't like they were singling out Ho-Sang. They probably saw less upside in MDC over any of the aforementioned players and weren't concerned that a lack of playing time would hurt MDC's growth.
If Ho-Sang had just reported to Bridgeport and put in the work, when the Isles had a quick run of injuries early on, Ho-Sang probably would have been one of the first call ups. Instead he complained, asked for a trade, made a nuisance of himself and was asked not to report while they tried to find a trade for him. JHS and his agent gambled and made a mistake because no one wanted him for free or via trade.
This article, with lots of direct quotes from him, documents many issues and problems:

These are Ho-Sang's own words from the article: The Islanders are trying to find a balance between these two sides of their young prospect, and Ho-Sang is trying to find a balance within himself. “When I came into this league, I was a little shithead who was growing into a bigger shithead, basically,” he says. “I just wanted to hang high in the zone and chill for breakaways because I thought I was the best player on the team. I’ve definitely been tough to coach. But I’m definitely getting easier. I’m working on it. It’s patience. And it’s frustration. It’s tough adjusting. I’m trying to play a more complete game, be a more complete hockey player. We’ll see what happens next.”
Clearly Ho-Sang overplayed his hand yet again and exhausted the patience of management. I believe there were also multiple benching in Bridgeport after Ho-Sang finally reported for both on-ice and off-ice issues. He just didn't get it in his time here.
