I suppose I don't have any particular problem with it, although if it's only Gods and Kings, the timing is questionable (if it's base vanilla Civ5, it's still questionable for timing reasons, but for different timing reasons... it'd be like making Bill Gates or Stephen Hawking a Great Person in that case). I do find it interesting that they chose Great Merchant. If they'd gone with Steve Wozniak, I'm pretty sure they would have chosen either Great Engineer or Great Scientist - probably the former.
Also not sure why this is in Off Topic instead of Civ5, but w/e.
A fanboy doesn't have to make comments all over the place, or necessarily bash the competition for reasons such as "not being able to do anything right", though that is one type. There's also the type that mindlessly buys all of the company's products, in the case of Apple likely because they are "cool", despite not actually using any of the features that they might offer over their competitors, and quite possibly actually being better-suited (either cost-wise or functionality-wise, or both) by a competing offering that they completely ignored. I'd consider people who buy iPhones and Macs simply to surf the web, make calls, send texts, and snap a few photos, when they could do so equally well for far less with competing products, fanboys/fangirls. They've paying for the logo.
I wouldn't include people who actually use software that only works on Macs and has no similar offerings elsewhere, or people who buy them because of a long and reliable history with the company (or a lot of existing Mac-only software), or people who use an iPhone/Mac but aren't terrified of being seem using a product without a piece of fruit on it. I also wouldn't automatically include people who said opposing fanboys have come out, since it is quite possible to suspect fanboyism without being one. But what computer they use, I think it does matter. If all you've ever used are PCs and Commodores, your Apple fanboy credentials are pretty weak.
There's the equivalent of fanboyism with other products, of course. The person who always buys Chevys even though their Chevys always break down, because they're "the best". The person who always orders Budweiser but hasn't actually tried anything else because they're "the best" (if they've tried lots of beers and still prefer it, that's different). Generally, it's whenever someone buys "the brand that's the best because it's the best" - clear cases of begging the question.
