I think you're right, but why is that? Not being snarky, or looking for snark--genuinely curious why this brand and not others.
It's the Disney lifestyle. A friend of mine calls herself a "Disney" fan. No other media company prompts that kind of top-down devotion. In saying that, she's a fan of everything "Disney", whether she means it or not. The films, the theme parks, television, all of it...and she's definitely not a shareholder. In that vein, all of their off-shoots and subsidiaries are under the same umbrella- you like one, you like 'em all, if you call yourself a DisneyNut. That's part of what's happening with Marvel -why we're talking about it on Disney forum spaces. That and the fact they've launched their most exciting film franchise yet coincidentally with the Walt Disney Studios merger.
Take UNIFanboys. They're really just Universal theme park fanboys, not Universal Pictures fans--or to really stretch to Disney's level, they don't call themselves Comcast fans. That just sounds insane.
Somebody likes Playstation. They don't necessarily "like" Sony.
Somebody likes Bugs Bunny, DC, Harry Potter. They don't say they're fans of "Time Warner Inc".
Somebody likes Frozen. They also like Mickey Mouse. It wouldn't be a stretch to assume they're fans of Disney Parks as well. They "like" Disney inc. 'Disney' is a brand. Comcast, Time Warner, News Corporation...are not.
In the same way, some are religiously opposed to anything Disney, but not other media groups.
It all stems from the influence Walt had on the entertainment industry, and even the name itself.
