Socialblade provides a rough estimate as to how much potential earnings can be monetized from YouTube videos. The monthly statistics provide a low and high end estimate of each days earnings based on views. The two 20+ million views are basically from his “bendgate” videos.

So at the low end, that’s over $20k in just a few days (his earnings potential is likely higher though). So yes, he can afford buying phones to bend.
But yes, this new video is amounting to milking “bendgate” for all its worth now where it is just noise amounting to first world problems. And it’s not going to have the same spontaneous viral effect the first one had. This new video is not going to change anyones opinion at this juncture either. Apple haters are going to run with it of course while this guy keeps destroying perfectly good/working product (he or whomever is sending/buying him these Apple iPhones just to destroy them is just one more sale as far as Apple is concerned unless of course, these are also counterfeit phones).
Note: the following video is a perfect example of something that can legitimately happen (it’s what I mentioned in earlier post with how clothing can bind and create a leveraging effect that applies more force). But it’s just one of very few legitimate postings in a sea of noise.
Apple will more than likely give him a replacement and be examining what phones they do collect
