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
Except GNU is a great example of an acronym that is pronounceable. It’s even in the dictionary. The GNU mascot is a gnu, in fact.
LGBTQIA+ is essentially unpronounceable, thus we treat it as an initialism. Not that that’s a requirement, there are examples like VIP where even though we could pronounce it we pronounce each letter individually.
This always seemed a bit weird to me. In Sweden we do pronounce that as a word. Vipp.
