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
The vacation one is a bad example because some people say vuhkation and some say vaykaytion. From the germans I know the E on the end is like uh, like how they say bitte, danke, etc
Bittä und Dankä!
