Again, Europe is far more densely populated than the US. The EU's population density is 106/km², the US is 37. The least dense country is Finland with 16/km², but they're a rich country with not a large population so it's not surprising for them to not have dial up. Runner up is Sweden with 24 but they are yet again a rich country. For context, there are 10 states in the US that have a smaller population density than Finland. Combine this with the US not having that good of public infrastructure because they mostly have private everything, I don't find it surprising at all that Europe doesn't have dial-up and the US does.
