I think net neutrality needs to be explored in a broader sense.
A free Net may depend on some wisely developed and implemented locks and a community ethos that secures the keys to those locks among groups with shared norms and a sense of public purpose rather than in the hands of one gatekeeper.
I'm a realist about how the networks work.
Strangely enough, the linking of computers has taken place democratically, even anarchically. Its rules and habits are emerging in the open light, rather shall behind the closed doors of security agencies or corporate operations centers.
In building a social network, the standards and mores of a community are its lifeblood; one does not lightly 'experiment' with these, and LinkedIn is exactly right to defend them.
As a result of transformation of power, functions of enforcement will slowly turn into new, networked systems of governance in the following directions: upward to the global level; downward to the communal level; and frontward to the professional level.
I personally like hard forks. Particularly, I like the fact that they give users a measure of control, requiring them to opt in to protocol changes. Sure, they can be a little more chaotic if they're controversial, but that's the price of freedom.
Internet governance is an oxymoron. The Internet must govern itself. But you can't play cricket without any rules.
