I mean... IDK. What was the illegal data that briefly was allowed to be accessed? Someone's CC info? CSAM? I'd feel different knowing exactly what I was criminally responsible for upon pressing that button.

It makes you litter.

Thought the title was talking about a bomb

That guy is seriously impressive.

I want that code for the carving using a 3d printer!

The data isn't accessable. The device is listed for sale (including the HDD with data: I'd guess SSNs because it is not illegal to possess another persons SSN, only to fraudulently use it and to sell it etc). If someone managed to buy it (in one of the brief, sporadic windows we can expect it to be for sale) the artist would still have to physically send the device to them before the data was actually in their possession, but by pressing the button you are participating in the operation of an illegal marketplace.

It's good art. And it's a good illustration of why minimum sentencing is a bad idea.

Part of the art is questioning how you would feel being complicit in the crime, though. And how I would feel about it would change depending on what, exactly, I am guilty of. I would be very okay pressing it if the illegal data was just a ton of pirated music, movies and video games. I would not be okay if it involved CSAM.

He says that the data is not illegal to possess only illegal to sell, so it's not CSAM. Also you don't ever actually possess the data, you facilitate its sale though.
