Part of the problem is the goalposts move. The cellular data connection you can get in many places (though, of course, not everywhere) is probably a lot faster than back when WiMAX was being promoted as the fix for the last mile problem. And typical cellular data caps today would mostly look like all the bandwidth in the world going back 15 years or whatever.
Now, a lot of people don't think they have "real" broadband if everyone in the household can't be streaming Netflix at 4K simultaneously without any meaningful caps or throttling.
The issue in Germany is that we're somewhat behind on mobile traffic caps as well. It's gotten a lot better recently, but it's still on the high end in Europe on traffic/cost.
