I've tried to find the actual court decision, best match seems to be 4 W 118/21 (enter on https://www.justiz.sachsen.de/esamosplus/pages/index.aspx under "Aktenzeichen" & click "suchen", can't see any obvious way to link the PDF...)

However, that document does not actually order a fine. It warns about imposing one ("up to 250'000€") if Youtube doesn't remedy the problem. Considering it's now exactly 3 months later (decision dates April 13th), that lines up.

From what I understand (not a lawyer, yadda yadda) this is a purely civil matter and doesn't really go as far as some statement on free speech. The issue discussed mostly seems to revolve around which terms of service are valid and how they can be changed.
