I think DICE should really give people a break. Battlefield 3 is a great game, but the modders really helped build the multiplayer scene in the first place. In my opinion, the only cheaters are the people who download auto-aim mods to demolish everyone else. (There are more examples, but I'll settle with this for now)

Besides, people are bound to eventually find the one gun to gain the upper hand over everyone. And yes, I am referring to Counter-Strike's stupid AWP.

"Maybe DICE is banning anyone from using this mod as it makes hostile forces more noticeable without the grey tint covering the player's eyes."

This article answered its own question.  You cannot allow anyone to have any type of unfair advantage in multiplayer.  Simple as that.  

To rebut that though.

"But if a player was just using this mod for single-player games, then it shouldn't be a problem, right?"

If I am using a mod in single player and I get banned, I would never ever spend a single penny on that company again, while doing what any mad video game nerd would do and tarnish them online in whatever way I could.

The bigger issue is the lockdown DICE has on the game. Unlike various other multiplayer FPS games like TF2 which allow you to create your own servers and play in non-sanctioned ways, there is no other option for players of BF3. So when something that comes out that improves the game (you should see how the game looks without that crappy filter on. So much better in my eyes), DICE can simply say "No, you play it the way WE want you to play and no other way". Now for MMOs where you're only leasing space on the server, this is fine, but for a game which (really should) be run standalone, this is disgusting.

Disgusting, and yet exactly what weu agree to when purchasing their 'license'. It's the same story as hundreds of other software complaints, just with a different lick of paint... Geddit?

Sandy's right. Consumers should be aware that, even though a game might be on the PC, not every developer is fine with consumers modding their product. However calling all mods a hack is disrespectful towards people that work on these mods. I'm pretty sure a big chunk of modders will avoid any game of DICE in the future if this kind of decision continues.

Absolutely. It's simple PR. Calling any part of your audience cheaters (even genuine cheaters)--ESPECIALLY a part of your audience which is by design more 'connected'--is going to have ramifications.
