That they deserve some good legal troubles for their behavior is another discussion entirely (Swisscom, which was doing the same thing as DTAG and running a collab with DTAG for a while, actually lost a few court cases over things like that). However that's not my point. My point is that the service DTAG offers is just inferior and people that were never exposed to something better (be it never tried or just got unlucky with the alternatives when they tried), just stick with it. I would never get internet from them in Germany simply because I value having good internet connectivity (not just germany-net) and want data to flow a little bit faster than during the isdn-dialup days. The mafia-like behavior (of requiring payment from hosting providers to get usable connectivity to their customers) is just the cherry on top.
