Speak up internally, sure. Externally?
I suppose it depends on the specific role, but oftentimes your job is to advise, not to win.
Or speak out publicly. Always an option without making any drama and being professional. [FTFY]
It scares me that so many people in this thread can't (or unwilling to) differentiate between creating drama and being proferssional.
You? Google?
The person giving you money is allowed to decide whether they want to continue giving you money. Similarly, you are allowed to decide whether you want to continue taking the money.
If google is acting unethically then I, as a user of google, want to know so I can hold them accountable.
Otherwise having an “ethics committee” is just feel-good marketing signaling at the same level of privacy terms stating how google, the ad behemoth, “cares about our privacy”.
