After waiting 20 seconds for that page to load for some reason, I scrolled all the way to the bottom without being told what it does. It appears to be some sort of foundation that provides grants to open source projects, except given it's "web3," I'm guessing that means it isn't actually a non-profit so gives none of the tax advantages a real foundation would give, doesn't have a board with a non-financial interest in the mission the way a real foundation would, and pays creators in cryptocurrency, which is a much less predictable and usable funding source since it varies so wildly in real currency denominated value and needs to be off-ramped to real currency to actually pay your developers and energy bills and what not.
