You seem to be confusing what the term "relevent" means re: down-voting. (or perhaps just want down-voting is for)

down-voting is a community moderation tool, to be used on comments that are off-topic, trolling, spam, etc.

The article in question is about AirBnB's repsonse to the situation (or rather, about EJ's comments about their response to the situation). The comment you down voted is making a point about a possible reason they may be acting that way.

It's a direct and thoughtful response to the topic at hand, it's ipso facto "relevent" in the sense that matters re: down-voting.

The fact that you disagree with it, or think it is flawed is not a valid reason for down-voting; instead you would reply refuting their point. You seem to think that their comment is not "relevent" re: how one considers their actions...and that may be true...but that is not a valid reason to downvote and not the sort of relevance that matters re that.

I only bring this up because many people seem to be confused about down-voting, or abuse the system and I think it's helpful to have a dialog on it occasionally.
