While that is just a natural reaction to "unfair" world where not everyone gets the same level of access to the best level of care, I'd also say that it's a reminder that money can't and won't solve all problems people are hit with in their lifetimes (or he'd not be facing cancer diagnosis in the first place).

This story is of someone with resources putting them to good use to save themselves, but also have that benefit others: medical research is expensive and for good reason restricted, and just like lots of open source was driven by individual's need, so lots of good stuff can come out of this. I suggest to see it that way.
