Not really. He's owed stock for what, 30 years? He could've said that starting from January 20xx (2 years after this announcements) I will automatically sell XX Million shares a year for diversification purposes.
But why give the IRS and the state 50% of it via taxes? He gets a nice chunk in dividends at very low taxes. And the mega rich borrow against the stock so when they die that debt is taken out from the estate without paying taxes. (Ellison got an earful from his accountant for doing so, lotsa debt and refusing to sell his shares. If the stock crashes, you're royally f-ed as the bank demands new collateral...death spiral etc etc)
