Yeah, I keep saying this too. For comparison: http://imgur.com/g0eYPCc this is my allowance for my mobile with Three (a mobile provider in Ireland). It's called unlimited (but I guess they put in a figure of 2 TB in the field just to put in something. I regularly pass the 50GB mark and never heard a complaint from them.
I can't say for certain it influenced people, but I'm happy to and regularly do recommend my provider to people looking for a good provider. It might be intentional that Three never bother me, because as one of their customers who uses a disproportional amount of data, I act as an ambassador for them. Very recently, during the Steam summer sale, I almost hit 100GB in a month downloading newly bought games. Not a peep out of Three.
