Sci-hub is about the most solid comparison I can think of (given a few moments to consider the comparison). But it's not quite right because the articles being shared are from research done for the public good which were typically already paid for by the public good. In the parable nobody paid ahead of time for the future possibility of the miracle feeding everyone. But that's a difference in the opposite direction from your "ethically dicey" comment. Jesus' miracle was way more radical than doing an end-run around an anachronistic business model to redistribute research the public already paid to get.
