Originally, it was envisaged that all services provided by the DWD to the general public for public dissemination via modern means of communication, such as mobile devices via an app, as specified in Section 4 (1) DWDG should be free of charge (Explanatory Memorandum to the Government Draft of a First Law Amending the Law on the German Meteorological Service, BT-Drucks. 18/11533, S. 22). The Bundesrat has commented on this and raised competition law concerns about the tax-funded DWD making meteorological and climatological services available to the end consumer free of charge, because such a free charge constitutes an impediment to established private-sector providers and erects barriers to market entry for new providers or new offerings (explanatory memorandum to the government draft of a first law amending the law on the German Meteorological Service, BT-Drucks. 18/11533, S. 25). The version of Section 6 (2a) DWDG that has become law is based on the resolution recommendation and report of the Bundestag Committee on Transport and Digital Infrastructure (BT-Drucks. 18/12836, p. 2), according to which not all services provided by the DWD to the general public pursuant to Section 4 (1) DWDG should be free of charge, but only those pursuant to Section 4 (1) Nos. 3 and 7 DWDG.Though then again not that surprising that they manage to publicly fund something and then ruin it, leaving the taxpayer in the worst condition. I believe there’s even no official source of laws online in Germany decades after the internet has made it cheap and easy to provide access to information.
Edit: not directly related but a fun fact: in Switzerland you can get a copy of the constitutional laws for free at any bookstore and it’s supposed to be understandable for normal citizens and not only for lawyers.

It seems that the Austrian way is much better though.
The person with the most freedom of speech in their bank accounts should be able to have the most say in how the government runs. Because they have most freedom of speech at stake.
So I guess I'm saying that you can already build such a system yourself quite trivially...
