In places where there are rules and order, and these things are valued, only important people are allowed to capture Sharpedo.
Even when captured, Sharpedo are treated with care, brought back to land, their fins cut and sold at a high price, and every part of the fish is eaten.
Even the bones are treated carefully, respectfully, and with love.
In such places, the lives of many Sharpedo are not lost unnecessarily, and valuable things are treated as valuable.
In the current capitalist world, which lacks rules and order, people on massive ships capture more Sharpedo than needed, cutting off their fins and throwing them back into the sea while still alive.
This way, they procure them in large quantities and sell them cheaply.
This is meritocracy.
What's wrong with the strong killing the weak?
The former represents many places and values in the Pokémon world.
This time, however, Team Galactic holds the latter worldview.
In other words, they represent the excessive and extreme aspects of the real world.
What does this have to do with the leaks? Was this a part of it?
Yes. There are a number of short stories included in the leaks. Most of them are in the style of Japanese folklore. For example, there is a story where a female Rapidash becomes a human woman and marries a human hunter and teaches him to only hunt adult, male Rapidash. This one is more modern in tone.
This represents the free riding problem of common resources. A common resource have competitive consumption but no method to restrict consumption unlike Capitalism which assume that all goods are private goods which have competitive consumption and enforceble methods to restrict consumption.
