Meaningless. These are people that are used to getting things for FREE. They’ll pay for a few months and then NSF the bill.
The way Comcast's system works your Internet gets automatically shut off the day your bill is late. It happened to me 3 months in a row when they messed up my automatic payment plan. I ended up dropping them a few months later, not because of speed or service but because of their download cap. Switched to AT&T's U-Verse because they had no caps. Naturally they changed their policy to the same cap as Comcast a few months later but AT&T is still better than Comcast because they will just charge you more money while Comcast will warn you then suspend your service.
