I always thought those whoe said susa instead of soos are wrong.
Suse stands for “Software und System-Entwicklung” https://linuxiac.com/opensuse/
Edit: Yes, she can still be wrong but then it’s supported by the rest of susa’s staff https://youtu.be/RsME20zXbQI&t=13
And that’s totally fair, in my opinion. Speech has to flow in the language you speak, or you’ll sound like an idiot. As long as people don’t go around claiming to know and teaching others pronunciations for things that they themselves don’t pronounce the way that was intended.
