> It shouldn't be too hard for the gov to commission a RosettaStone like german learning app ((suboptimal, i know)) that works somewhat well and give it out for free, right?)

Deutsche Welle (DW) is funded by German taxes and has materials for learning German: https://learngerman.dw.com/ as well as regular new materials aimed at learners, such as the news spoken slowly https://learngerman.dw.com/de/langsam-gesprochene-nachrichte... -- although I found it easier to listen to the normal news (e.g. tagesschau) slowed down slightly. (W-h-e-n p-e-o-p-l-e s-p-e-a-k s-l-o-w-l-y i-t c-a-n b-e h-a-r-d-e-r t-o l-i-s-t-e-n t-o!)

Not state-funded, but I recommend https://www.easygerman.org/ -- they have lots of good youtube material, a nice podcast, and an app I've not used. Most of the material is free with bonus materials for supporters.
