I'm sure deep down, Nerf doesn't mind mods, but they've gotta mention how they don't approve of it on the blaster's packaging because of safety reasons.

As for third-party darts and accessories, they probably do mind, because it takes away their money, especially the darts (because Hasbro needs to make the money off of their more expensive yet less-good darts).

Maybe not so much with cosmetic kits (most of them require you to buy the blaster first, anyway), but I'm sure it can't be healthy for their PR if someone started seeing a kid wandering the streets with an all-black Stryfe dressed up in realistic-looking tactical furniture.

So basically:

Mod community: Probably okish, if they aren't doing anything outlandishly dangerous. Plus it boosts popularity like BigS said. That being said, if someone's blaster stopped working and they opened it up and made it work again, it would probably make Hasbro sad, because they were hoping that the consumer would just buy another one instead.

Cosmetic items: Not very okish.

Third party darts: Very not okish. Think of all the money Hasbro has lost because some Chinese company made cheaper darts that perform better than Elite darts.
