u/There_is_not

I've just moved from a small apartment into a house, and we're currently paying $35 a month for a 500mbps plan metered at 5Tb/month. It's been easily plenty for 'lil old us, but I've been getting ads for google fiber, so I checked the website. The ads I've seen advertised 1 gig for $80.

Now, what's the catch? Free internet? At 1 gig, nonetheless??? Is there some sort of byte/bit discrepancy? Regardless, free internet seems impossible. How? I checked the broadband facts, and there doesn't seem to be any other fees. Sooo...

(sorry if there's a duplicate. I made a mistake in the first post)
