I don’t use revanced, but freetube. I guess it’s similar.

It lets you play video without ads for free. It has a ui close enough to YouTube, which is nice.

Also you watch video anonymously. So it won’t propose video based on what you have watched before. Which is nice or not… you decide.

What about the components? Should they also be produced in the US?

Let’s be clear, producing the iPhone in the US would be more than a 25% cost increase.
