Lyft donated 1M to the ACLU. That's pretty different about taking action.
An analogy: a company has an oil spill, so they donate to Greenpeace.
Further, 3mil to their own drivers (which I haven't heard about but whatever) doesn't change US law -- so if their driver is booted out of the country, a few thousand dollars ain't much if you're thrown into a civil war or worse.
