Public universities do the research, public money builds it, modern communication depends on it, and now corporations own it. Please, can we stop calling this [poo] 'capitalism'?
The internet has always been rooted in socialism with private industry allowed to profit from it, and that's the way the vast majority of industries in the US work. The whole military industrial complex is like one big socialist technology research center which gets privatized so companies can profit from it.
There is no such thing as a pure capitalist society and there never could be and nobody would ever want it. People like some degree of stability and capitalism depends on instability for efficiency. There will always need to be a mix, and there's a legitimate debate on what that mix should be, but calling all socialism bad is just plain wrong in my opinion. As long as we allow competition, entrepreneurship, etc - we are still a capitalist society even with plenty of socialism.
Some socialism is necessary, good, and works great. Our country couldn't function at all without it.
Some here are very extremist and far outside the mainstream with what role they think government should play. Some here think social security and medicare are horrible socialism, while the vast majority of Americans think those are the most successful and needed programs ever created.
Back to net neutrality, Toad is basically right. Comcast came half an inch from blocking Netflix. Rules saying ISP's can't block legal content ensures a relatively free internet like we have today. The rules are very weak though, ISP's can still discriminate against competitors, speed up traffic for itself and partners, etc, they just have to disclose what they're doing. The rules did nothing for the wireless spectrum, so anticipate a lot more fragmentation there.
