>What you're doing is like watching a boxing match and saying "it's very lazy that these people aren't using their legs" or "I don't understand why that person won, they didn't even knock the other person out!". There's a thing that's happening here that you've not bothered to learn enough about to understand whether or not the participant is accomplishing their goals
But, you see, art is not a game. There are no rules. If you paint me a portrait of myself with your feet and you make me look like my mother, I'm not going to be impressed that you managed to paint my mother with your feet. I'm to ask you why you didn't use your hands, you dolt! If you handicap yourself to the point you make something bad, then it's only fair the results are judged on their own merits, isn't it? If you wanted to use your feet to entertain yourself then any criticism you receive for it shouldn't matter, because the activity fulfilled its purpose to you, the same way boxers don't care about the criticism they receive from people who think they should also use their legs.
I don't care about their goals. Their goals are for themselves. I don't need to know them to judge the quality of the result.
>"I don't understand this" (although I'm getting the sense I'm unlikely to hear _that_ from you)
I'm honest enough to say I don't get the point of the soup can. That doesn't stop me from saying it's low-effort. I see better art on Twitter every day, even though most of it probably has less of a message.
