For me, the reason to wish for a higher download limit is simply that I want to watch videos from the major studios in the best quality available. I don't have the intention to collect any videos. If there is a Virtualrealporn video in 50 Mbps, I want to watch it in 50 Mbps and not in 22 Mbps reduced quality. If there is a FuckPass video in 90 Mbps, I want to watch it in 90 Mbps and not in 30 Mbps.
I think most will be able to accept that downloads cannot be unlimited. But if you look at the fair use policies of other providers, the lowest I've ever noticed was 10 per day. Therefore, I think that asking for 10 per day instead of 5 is not an excessive demand at all.
