Correction: you either choose to believe that's the symbolism, or you don't.
I "get" it, intellectually, but I don't think that was the intent of the advertiser, nor do I think it's the obvious interpretation of the ad. The obvious interpretation, to me, was "hey, we can piggyback on this hydraulic press channel meme and sell iPads!"
Tellingly, few people care that the hydraulic press channel exists, despite actually crushing all sorts of stuff [1]. See also: the viral "does it blend?" ads [2], and any number of music videos or performances where instruments are destroyed [3] (practically a meme unto itself), etc.
[1] including instruments (listen to the guitar 'scream' under the press!): https://www.youtube.com/watch?v=zsQOKKE7UbM
[2] they blended a skeleton! oh, the symbolism! https://www.youtube.com/watch?v=AsTZm7QtY84
[3] boom go the guitars (this, apparently, was not the one moment that mattered): https://youtu.be/QvW61K2s0tA?feature=shared&t=175
