I believe people who are in the arts see those tools as an extension to the body. Plus, not everything that was crushed can be replaced by the iPad. For example, the iPad makes for a terrible big television screen replacement for example, since you can't have a group of friends over and watch a movie or the game on the small tablet.
Well, neither does the Apple Vision Pro replace a TV (it also excludes the people around you) and they advertise it primarily as a super mega cinema screen.
In the end it's marketing, you can't take everything at face value. But nowadays if you go a little too far (I don't consider this ad to be too far at all, it's just an ad, that's all) there are already hordes on Twitter crying and feeling offended.
The iPad is a device designed for creatives, and with this ad they want to make the case that it doesn't replace, but can do “all that” and more. You can draw, you can compose, you can edit, you can play games, you can watch TV, you can do many things with it. To go to the point of feeling offended by smashing inert objects... seems absurd to me, under my occidental point of view.
