Net neutrality is about getting exactly what you pay for. For example if you pay for 100MBps connection you should get 100Mbps regardless of any site you access. You don't want your ISP to decide that Netflix would stream on 20Mbps and Comcast would stream at 100Mbps. This gives us unfair advantages to certain sites which is beyond your control. Worse yet ISP can police which sites you can visit which not with absence of Net Neutrality. So this has nothing to do with communism or also not to be confused with the "right to free internet". Those are all independent topics.
