Let us start off by providing an overview of the Foundations financial situation. Its current holdings are roughly:
200,000 CHF
1,800 BTC
2,700,000 ETH
They need to show when they sold the 8m ETH. If they did it at the start while warning others against transferring that is a clear theft.
Does Ethereum Foundation have any monetization plan? How much do they make in donations for example? Is it enough to keep development forward?
Read the blog, Vitalik expects others to come with their own for profit ventures.
