Different people have different licence preferences. "Why this and not that" questions usually don't spark joy. (Might seem fine for the individual who asks it, but not really in a community.)
You're also entitled to not comment on discussions you're not interested in. License discussion is very much relevant for anything that might end up being used for data interchange.
Having been annoyed by people who asked me to change license several times, I have no sympathy for these requests.
