More open action is necessary, I think to properly remind the FCC of why net neutrality is critical, but a demonstration of the potential for abuse of a "Fast Lane" policy is a good start.
I imagine their reply (should one ever arise, either directly or more broadly) will be something along the lines of "We [at the FCC] will review each case to ensure fairness and commercial viability." since that's the most obvious avenue of deflection.
And the matter will then fail because of three issues:
1) Exactly who decides what is "fair"? Lobbyists? A hardline policy formula? A delegation?
2) Even assuming we could trust the FCC entirely to maintain fairness in their judgments, the policy would create an incredible burden on the governing agency to maintain it.
3) "Fast Lane" policies currently aren't necessary. Content providers and ISPs are experiencing an incredible protracted boom in business on the whole. Few to none would "need" such a policy, and it would unquestionably be more costly to the economy in the long run to implement it.
Oh, but there I go trying to preach reason to lobbyists seeking to undermine the public interest for their own profit.
