Everything is politics. Science will never and can never be apolitical because it says things which one political party or another will either like or hate. But further, very wealthy and powerful people have a vested interest in making sure people don't trust inconvenient truths.

Climate change is the poster child for this. We predicted the weather problems and patterns of today when I was a child. But because that truth was inconvenient to the fossil fuel industry, they decided to spend ungodly amounts of money buying conservative politicians and broadcasters to lie about what the science said. And here's the thing, that worked. Their politics overrode good science and science based policy.
