Please post rationale as to why Netcodes is problemmatic. Else I must assume there is no rationality.

It doesn't work very well with your average Joe.
Net = Internet. Fine.
Net & Codes = something that sounds like a voucher or discount coupon.
Yeah and that is good. Why do you think that is a bad association

Not only that. Gaming codes are sometimes akin to secret recipes.
On the one hand, net & codes could be associated with some marketing schemes such as Groupon, and on the other hand it can be associated with network programming and every gradation in between such as gaming recipes and Unicode emoticon recipes (a limited form of actual programming).
The entirety of the internet is comprised of tangible network infrastructure, virtual codes, and human interaction thereof.
Its
all about the codes man, no trouble. (Dance music and sex on the dance floor is all about the bass/beat and not the treble).
It just wouldn't make sense to the average person, especially when they are transacting with each other. Than you'll have an issue with businesses transacting with customers.
Business - that'll be 10 Netcodes.
Customer - Ok. Can I use my coupon code to reduce the cost?
Business - sure. 10 Netcodes, less 3 coupon codes. That'll be.....yeah, one too many codes.
