It's an effort based on the paranoia that one day, big companies might one day force users to use one web service over another. For example: Hypothetically, some day far off into the future, users of MSN's internet service will only be able to search with MSN Search instead of Google, while users of Comcast can only use Yahoo and not MSN. Users might have to pay more money for what they get now for free.
That's the fear. It's not reality. This "problem" doesn't exit. Free market is reality.
Anyway, Net Neutrality would pretty much guarantee that this scenario could never happen by placing laws, restrictions, etc. on ISPs preventing them from doing this, even though they're not doing it already.
Sounds like a good idea on the surface, but a waste of time in reality. They're trying to solve a "problem" that doesn't exist. Instead, spinning their wheels on the "what ifs" and "maybe's"
I've seen bass clubs drive themselves into the ground by creating tournament rules for situations that have never happened. They spend too much time wasting their efforts guarding against paranoia, rather than tending to the needs of the club members.
This is why Net Neutrality has gone nowhere in 7 years. It would be a lot of effort to solve nothing. There are bigger things to worry about in life.
Moving on....
