Curious as an outsider what you mean with US politics? Seems like Apple has a pretty strong stance when it comes to things like privacy that pushes back on some things (that could be smoke and mirrors though I guess).
Depending on who you talk to, this could go either way. Some people want big companies to champion their own political ideals on a larger stage and think Apple should do more. Others would say Apple should stay out of it, after things like their gift to Trump[0], for example.

The privacy is more of a market position thing than it is a political thing.
Apple has led the industry on hardware but is woefully behind on the software and services front. Focusing on device-level privacy controls turns what would be a gap into a moat, and it helps deprive Google and other services from monetizing their customer base.
Not to say that it's not something the company is passionate about - but it's also good for their business. Especially when you compare it to things like human rights, transparency, and security research where Apple could take a stronger stand but don't.
