I’ve heard it explained that “hey” used to be more of an urgent way to get someone’s attention, rather than a casual “hello” like it is now, so it sounded rude to some older folks.

The implication is that a problem was assumed until “no problem” was stated.
“No problem” is absolutely low key rude.
To me, ‘No problem’ is just short for something like “oh don’t worry about it; it was really no problem at all and I’m happy to help”.
Colloquialisms are fun like that.
I feel that kind of interpretation is more region specific. Specifically, West Coast?
Midwest, actually!
