No one is actually upset about any specific objects that were destroyed in the making of this ad. This sort of advertising is all about eliciting emotions and shaping a message--a vibe--about a particular product. This ad triggered visceral feelings related to the emotional connection a lot of people--even skeptical agnostic materialists!--have with the tools, instruments, and products of creativity and art. And based on the reaction, the ad clearly elicited a lot of negative emotions and a negative vibe in what is presumably the iPad Pro's target audience. Thus, I'd say that even from your ultra-rationalist point of view, it's a bad ad.
