What have Hoffenheim and Leipzig done for the league? Bundesliga's pitch is authentic football with big and enthusiastic crowds, e.g. Frankfurt showing up with 20k fans abroad, plastic clubs go completely against that.
And this isn't about Hamburg and Stuttgart in particular, that's a fat straw man, those two got themselves relegated with bad management, they got what they deserved, no one is arguing that rules should be bent for them.
How are they even showing how to run a football club? Should Bayern expel all its members bar 13 and run a network of feeder clubs? Perhaps FC Bayern Qatar is Rummenigge's next step in his ambition to improve human rights in the region? Wouldn't it be great if traditional rich European football clubs take a page out of Leipzig's book and start colonizing the Americas, Asia and Africa?
How is Hopp pumping €400m into a village club different from City's people pumping €2bn into an established PL club? It's just a smaller scale.
How is buying entire youth teams from other club great for the region? How is Hoffenheim's great youth work paying off when the only notable player that came through their academy is Süle, who played for both Frankfurt and Darmstadt before they signed him?
How is Hoffenheim's region one that has been ignored for to long when Stuttgart is 60km away and Karlsruhe even less? Hopefully some kind and benevolent billionaire will open up a club in Bad Wiessee to help the football starved region around Munich? RB doesn't give two shits about Eastern Germany, they tried to buy in at St. Pauli, 1860 Munich and Düsseldorf, before eventually picking Leipzig.
