Not that I like Verizon and Comcast but they are only regional problems. They don't operate everywhere in the world.

In many countries, a lot of large ISPs are the inheritors of national monopolies and are not overly interested in global domination. They are shit, yes, but at a smaller scale. In this regard, they don't really pose as a threat to the idea of open internet.

Of course the US ISPs have a special place in the system and shouldn't completely be forgotten but they are very far from the global domination of Google et al.
