The idea that increased horizontal field of view is a 'cheat' and a 'hack' has been popular among those unable to afford widescreens/EyeFinity/Surround since the earliest days of widescreen gaming on the PC.
For example, after a lot of fuss when Battlefield 2 was launched, DICE used to think increased horizontal FOV was cheating. This was because hundreds and hundreds of kids couldn't get over the fact that there were people out there who were buying the (at the time) extremely expensive 24" widescreens from Apple and Dell (who were just about the only manufacturers for consumer-affordable desktop widescreens for a couple of years). DICE finally changed their stance with the final patch for BF2, IIRC, and of course BFBC2 allows FOV change to a degree.
Epic Games refuse to change their mind about it, as it happens. Which was quite amusing, considering that Unreal Tournament 2004 supported horizontal FOV increases correctly, but they hard coded in what we term 'vert minus' widescreen (where, instead of seeing more at the sides compared to 4:3, you see less on the top and bottom) in Unreal Engine 3. They came up with multiple reasons over the years, beginning with 'its cheating', leading to 'its a bug' then 'a design decision' then back to 'its cheating' again, before finally sticking to their guns with 'we code for the 16:9 HDTV resolutions, so if you play at 16:9, that's the way it's supposed to be, any other way and it's not how we intended it, so we won't comment'. This has been a major thorn in the side of Surround gaming over the years, as while you can
just about live with it on a 16:10 screen, on triplewide it means you're looking through a very thin, slit letterbox.
The amusing thing about the hypocrisy evident by the gamers who are anti-widescreen is that they're quite happy for widescreen gamers to see less than them vertically.
I would mention the forum which has spent years lobbying for true widescreen/surround support, but can't decide whether I'd be breaking the TOS or not.
By the same logic the anti-widescreen group has, any peripheral that gives you an edge should be considered cheating. A keyboard with macro keys. A high-DPI gaming-grade mouse. A fast graphics card. A better CPU. A faster, low-ping 'net connection. 5.1+ audio. Good eyesight. Better reflexes. Etc... etc...
