No, they should mod you up. It is easy to write snarky and cynical comments... they can generate them without having to RTFA. Obviously Facebook makes its money on eyeballs / participants. Why can't this just be a win-win? By expanding access to higher speed internet, Facebook increases its potential market. What's the difference between that and increasing distribution of any product a segment of the marketplace needs?
The USA Highway system was built in part by the distribution needs of corporations. But we are all free to drive our cars and motorcycles on it. Should we not have built the roads because a corporation was going to profit from it? It's called "development".
