SunRocket and Consumer Recourse
It does seem some subscribers did the math and realized SunRocket, nor likely Vonage, are tenable the way they are/did business. It's true, given how they're structured, the more people they sign up, the more money they lose.
I am not defending SunRocket, but:
The other interesting observation was of the customers that were very, very upset at the sudden loss of service. Talks of calling the FCC or other government authorities were bandied about. What these people don't realize is that the government does not owe them anything. For one, VoIP as structured, skirted the tax structure of traditional telecom - this is where the deals came from. No tax, no government regulation = no recourse. With the imposition of some regulatory fees came some recourse, but much of this was because the telcos granted area monopolies were seeing their best customers skimmed off by VoIP, and thus successfully argued that this eroded their ability to provide at-loss telephone service to out of the way places.
Remember - a normal telco, say Verizon, is granted a monopoly in an area in return for not turning down customers. This means if you live somewhere where they need to string wire to you, they cannot charge you more than the guy in the downtown apartment. In return, nobody can go anywhere else. Those calling for government intervention circumvented the system, in almost all cases, knowingly. "So you left for the high seas to get away from your navy and customs people, and when the pirates come, wonder where your navy is?"
Now, you can knock SunRocket on consumer laws, but most of these only take effect in the case of outright fraud, are difficult to prove, and moreover require there be assets in that company to allow the damages to be paid. Which means that if you do take them to court, even if you win, no matter the size of the judgment, there probably won't be enough to take to even pay your lawyer.
In the end, people, knowing what they're in for, can either accept the risk of going with VoIP (or this new-fangled thing called the Internet - your virus checkers are up to date, right?), or return to the traditional, sheltered telco environment. It's a free country - you're free to complain too.
Just be sure you've got your number porting paperwork in.
