I can't really believe that people get so tribalistic over Gateway... oh, wait, yes I can, because humans are instinctively tribal, we can get tribal over anything and everything, in fact, it's harder not to. Basically impossible, even. Best you can hope for most of the time is to tribe up based on what the facts and your logic tell you.
I suppose I had that in mind when I said to myself, back in the day "Hm, this 'Gateway' looks like a whole lot of rubbish. I'll commit to modding when there's an actual solution that isn't made by amoral businesspeople."
When I see Brickway unironically place highly destructive copy protection on their piracy card, that only confirms my initial suspicions. Even the most draconian of copy protection from legitimate companies never blew up your system for trying to use a counterfeit dongle. There's no reason why Gateway couldn't just make their loaders yell at you, except for pure amoral greed. I suppose you could technically run homebrew on a Gateway, but it's designed for game ROMs. Joke's on them, it's easier to pirate with CIAs, too!
Do I care if the people working there found some of this stuff first? No, no I don't. The fact of the matter is, Gateway was closed source too. And not even because they mistakenly believe that digital piracy somehow tears chunks out of actual sales, rather than mostly being stuff the pirate would never have bought anyway. I can respect that view, even if I disagree. That combined with the brick code that did hurt "legitimate" consumers - patch or no patch, this isn't some Lumiose City save softlock, this is a bricked system. Gateway are nothing more than fences of the digital era.
For any lurkers, ignore Gateway. Pick up a proper CFW installation, ignore the apologists, and use NTR if you want hotpatching, cheats, N3DS video streaming, and all the goodies. There's a multitude of good reasons why it's "hip to hate on Gateway"
You could compare it to hating on feminism, except that Gateway was at one point the best solution for first-adopters, amoral or no.
