You can give away a lot of money while still making more, particularly in a year like 2020. I don't think they thought they were agreeing to give away half of every future dollar. They are giving billions away, and trying to look for ways to condemn what they're doing is only punishing a good thing. Never punish a behaviour you want more of. PS the tax deduction thing is envious garbage - you can only deduct the amount of tax on the dollars you donate (ie your top marginal tax rate). So you have to lose a LOT more than you "gain" through deduction. You don't come out ahead. And you should never have been taxed because you didn't keep the dollar.
