I have a feeling that there'll be some privacy related conditions attached?
I can't see why they'd give a connection away for "free" otherwise - surely they have some clause that you'll have to use their DNS servers, or get served their ads?

But anyway, unmetered 5/1Mbps is damn good for a "free" service - assuming you can amortise it over 2 years, it's like $13/mo with no setup fee.
Is gigabit 1000Mbps in both directions?

Also interesting is the TV package, but then IDK what cable is like in the US.  $50/mo for TV would be quite expensive here.  I'd imagine it'd be the most attractive to people who don't stream stuff, but then they wouldn't really use the gigabit connection?
