Well, certainly in developing countries where bandwidth is limited, you're going to be watching a small resolution, and any amount of CPU is fine so long as you can cut the bitrate. There are a lot of people in places like that. Also

In that case, DNSSEC probably isn't doing much for you (besides the systemic effects of discouraging providers from returning false DNS results in the first place), but sadly not everything on the internet is so well-designed as ssh. B
