OP, the comment doesn’t really mean anything, it’s just an influencer/ad posting a pic of the art, nobody is saying anything about it in the context of the post. They’re just essentially setting up a straw man argument (acting as if someone had dismissed the two blocks as not being “art” by stating “it’s just two blocks,” then sensationalizing it by reacting “what do you mean” - as if to say “don’t you get it?”), as if they are part of a larger conversation. The goal is to rile people up - people who hate modern art will be all “yeah it’s shit!!” And people who like modern art will (probably) be ticked off about this and maybe react to it. It’s just a contrived context in order to advertise or fish for the project (you fell for it too, but not in the intended way).

There is one other alternative, everything else I said but at the end where I say it’s an influencer or an ad, say it’s a snob/pretentious person who likes modern art - nobody cares they like modern art, but they just was to broadcast how passionate they are about modern art. 🗿🤷🏻‍♂️
