> $70 for 1gbps rather beats that by a drastic margin.
You need to factor in the marginal utility of added bandwidth. Few people can meaningfully utilise 20-50mbps (a full HD stream is <10mbps), much less 1gbps, so you're looking at paying $20-30 for, essentially, nothing.
For the record, I count myself in the group of people who can't utilise such a connection, although I'm squarely in the group of people who'd pay for the faster connection in a heartbeat regardless.
In Utrecht, Online.nl is ~$54 for 50mbps fiber.
Fiber.nl is ~$44 euro for 50mbps fiber.
Per https://www.internetten.nl and online.nl
$70 for 1gbps rather beats that by a drastic margin. Many cities in the US are seeing gigabit consumer fiber deployments at that price range.
