Not a tax break for the employee, since the net effect is still less money. Unless you consider losing your job and having no salary to tax also a tax break.
I doubt anyone was thinking about donation related tax breaks or anything like that. It was simply "sure I will have Google give $500 to this food bank, but why don't I get a new phone or cash bonus?"
If you're comparing against the employee getting a gift and keeping it, then yes, the employee was better off before.
But you're comparing against an employee who was previously donating the gift and getting a tax deduction on that donation, the employee is better off now.
