SE should consider providing its own VPN network to solve the lag problem

A problem exists with their product service, so it is their fault. Would you goto the grocery store, and buy spoiled fruits, and when you ask the manager about the spoiled fruits, he says "its not our problem, our vendor supplied them to us like that nothing we can do!"? They would probably (already have) losing customers.

Your analogy doesn't work. It would be more like an intersection on the way to the store is clogged because everyone uses it, so you complain to the store manager to fix it.
