It's not an invented problem. In Spain, ISPs like Telefonica and Vodafone are posting tweets are telling newspapers that people need to use the Internet with responsibility [0]. They also passed a law yesterday that allows ISPs to close connections if they know they're being used to spam the network.

Maybe in Germany is different because people are more used to work from home or just being at home while watching Netflix but Spanish people like to go out a lot and now the network needs to serve all these people as well.
