You have clearly elucidated the major factors in your decision:
1. Career / salary
2. Moral hazards
Taking into account what other comments have touched on, I’d say that you should be sure to weigh your own personal interests. Honestly I find it hard to believe that every engineer at FB believes that every decision FB takes is right. As others suggest - being part of the machine, you will have a voice and you will be able to have some impact on the world, and at the same time you might be able to advance your career and income.
You haven’t discussed the alternative options - what else are you considering?
Disclosure: I have had a FB offer but decided not to take it.
