That's a weird one. It's common for people to prefer the original audio, and most Germans understand English.

Germany has a very strong culture of dubbing essentially everything. Just finding any showing of a film in its original language at a cinema is very difficult outside of major cities for example.

With video I think that it’s sometimes a licensing thing. As in, the streaming service licenses subtitles from a third party and the rights are limited to specific countries.

Same in Spain. Often only the Spanish dubbed audio is available making the content useless to me.

With the increase in ads on streaming platforms I've just reverted back to piracy. The enshittification has gone too far.
