I think it matters more where I studied. First Heidelberg, then FU Berlin - actually Physics with secondary subject CS. TUM, KIT and RWTH are maybe the best at CS in Germany, but IMO still not good. What are they known for except being good universities for CS?
The fact that you are asking this question makes me believe that you are speaking without having tried to search for an answer on your own. As a CS graduate with secondary subject Mathematics from TUM, I can only speak on behalf of it. You might find https://www.youtube.com/watch?time_continue=194&v=iu6UboRqan... interesting.
How do you know that TUM is not good enough? Probably you are referring to its popularity abroad? Well its definitely worse than that of Stanford, Harvard, MIT, Caltech, etc. But heck, we don't have Hollywood to constantly make plugs in blockbuster movies to boost worldwide opinion.
I think that what he is referring to is the lack of big leadership in one (or many) tech sector .
From the examples he mentions, I know automatically (without searching for it) for example that Scala originated at EPFL, that ETHZ (& EPFL to a lesser extent) produce some of the most advanced things related to drones, that OCaml originated in France and is pushed by INRIA, etc... But there is nothing coming immediately to mind about TUM
