I mean, there's no coordination for fans or supporters groups because the teams and the leagues don't view them as such - they're only viewed as customers. It's an inherent mindset difference and something the NHL/Leafs will never overcome. So, yes, of course they'll hike prices, because there's demand for it, and people who are against it aren't organized enough to have any sort of impact.
Once you realize that NHL players come from the same types of families that are able to comfortably afford tickets/boxes at NHL games you'll realize that hockey at that level isn't for "normal", "working" people anymore. It hasn't been for decades.
