The issue is that Time Warner launched the Lakers RSN a year or two earlier, and they want the providers to double dip. If they bundled them for a lower fee per network, this wouldn't be an issue.
They totally misread the market, especially given the fact that there are two established Fox RSNs in the market already. I'd be pissed if I lived in LA, but I'd get it. They're not just clashing over a few cents here.
