There’s more than two groups. Some people are just being friendly, behavior which is hard to exhibit when you primarily (or only) interact with someone over chat. Yes, some people are just being nervous around potentially breaching etiquette in an ironic way that happens to be a different breach of etiquette (for some, at least) but I just respond with “hi” strictly because I am interested in getting on with the conversation.
It would be rude to simply link this site (not blaming you) in response to a “hello” coming from a remote co-worker, or even a co-worker across the office who just didn’t want to walk over. They are just being friendly!
I am one who would prefer to just get on with the conversation but I also realize that’s not how everyone is and that’s okay; I should play nice with others if I want others to play nice with me and a simple “hey” in response is such an easy way to play nice.
The context I usually saw this used in is that people would put the link on their online status or profile bio, as a signal and to inform anyone looking to contact them that it's ok and encouraged to just go straight to asking their business. I've never heard of someone sending it to explicitly "chide" someone for violating that etiquette.
