Mmmm, describing 50 Mbps down as "okay for rural areas" doesn't really mesh with reality.

Most rural areas throughout Europe and elsewhere are struggling with <10 Mbps, if they can get broadband at all.

If you know any region in the world which isn't densely populated, but where every home (not just 1 or 2) has 50 Mbps download, I'd love to read about it. I know of a handful of self-starter village communities which are doing this (e.g. B4RN in the UK), and that's about it.
