He didn't say he would give away 99% of his wealth. He said he would use 99% of their Facebook shares to fund their agenda. And he said they would do that with 99% of his shares over their lifetime... if they were 'giving away 99% of their wealth' they could just do that today. As it happens, they can still realize significant returns from those funds in the meantime, and probably end up richer than when they started. The pattern of manipulative billionaires sheltering their legacies like this is not new; see Rockefeller, Carnegie, Ford, Gates, etc.
