I thought about joining the network but it's a hard sell over Verizon Fios. 300/300 for $40 a month is hard to beat.
edit for context: in brooklyn
Now we're moving to Long Island and the town has only two choices - optimum and FiOS. When I looked at the Optimum statement, there was a ton of "discounts" for being in a high-competition area which is how they got the price down to ~35 as well, from the base of about $70 as you said. Though we later changed our minds and went for Fios at about $39.
