This debate centers around whether Facebook is a publisher or a carrier (like a phone service). There are some ways that Facebook inserts itself much more directly than a carrier would:
1) They control the feed algorithms.
2) They set policies around what activity is allowed by users.
3) They run ads at their discretion.
4) They control all of the application tooling, which in turn establishes what users can and can't do.
You can look at the situation as users asking for more control over those 4 points. We can do it either by breaking up the tooling and devolving more authority to users, or we can do it via government-regulated policies.
