Pine didn't deserve that kind of power as I'm sure they would acknowledge. (Otherwise why give it away?) They made money on speculation, not an activity that actually would produce expertise in philanthropy or would produce some other kind of legitimacy.
While Pine almost certainly didn't intend to do so, the PR from their gift produces a certain kind of effect. Namely, it provides cover for capitalism. It's a big attention grabbing move that makes it seem as though capitalism has a human face, all for the price of a few tens of millions of dollars in an 18 trillion dollar economy that is dominated by tight fisted oligarchs.
We should be routinely taking money from the wealthy and using it to produce results for the mass of people. Nonetheless, thank you Pine for being a good citizen of humanity.
