IDK about everyone else, but I pretty routinely bail out of the politics of decisions when it's mostly to the company's detriment. Starts to look like an uphill battle against people above me on the food chain? Sure man, go ahead, not my money you're wasting. The only politicking worth doing in those cases is making sure I'm outside the blast radius if it's something so bad it's gonna eventually blow up. Luckily big businesses move so slowly that this rarely takes less than a year, and often quite a bit more.
