The Fisherman logo is the "okay, boomer" of New York Islanders fandom. It tends to be triggering to anyone in the 50+ generation while the younger folks enjoy it. Obviously, that's tongue-in-cheek, but the fisherman logo is certainly a hot button topic.
People either seem to love or hate the logo, there really isn't all that much in between. Regardless, the Islanders seem to continue the embrace of the logo as "vintage" and a way to profit.
It makes a ton of sense, the 90s or vintage/retro merchandise is huge right now so when the Islanders released a ton of new hats with that logo on it, it created a ton of stir on the old twitter machine.
