This is a straw man. The core of the argument isn't about money being evil but rather that in large enough quantities it overrides ethics, especially if it's combined with lack of responsibility.
I believe that ethics are incompatible with capitalism, so this kind of personal choice doesn't change anything. You can change jobs from one evil company to another.
What would work is enough people willing to organise politically. Unions, people. This is a synchronization problem.

Yes, Google does unethical things. This sucks and I feel uncomfortable supporting it. Quitting is just too costly in terms of personal cost and would not have much effect.
