That is something that liberals would not find sufficient because liberals, for the most part, require government approval (read: funding) of their causes to feel validation. It's the same reason why private charities and companies donating billions to NOLA is almost completely ignored while almost all of the focus is on throwing more tax money at the problem. The same reason why private charities and shelters for the poor/homeless are marginalized while government sponsored charities are constantly being given more taxpayer money. It's as if liberals have it ingrained in their heads that anything useful and good can only come from the government, and that anything that comes from private industry is of little consequence. This is just the latest chapter in their book.
