> the other party owes you nothing.

No, that's an aberration perpetrated by software. The same problem has manifested in interviewing. Maybe you're thinking of "nobody owes you sex" instead?

If you greet a person in real life or over a call and they intentionally ignore you, they are being rude. Obviously, if you're being rude first, that's different. They can say "hey" back, or "sorry, I'm not interested" or "kind of busy right now, can we pick this up later?" There are plenty of options.

I understand that the way these apps are set up, responding like this isn't a winning strategy. Despite what the Internet would have you believe, there is a minimum social bar when there's a human on the other end of a comm channel.
