Both need to be taxed. And more. If not they'll find loopholes.
If we want to let common people off the hook, it's as easy as progressive taxing. The first million is free (or not heavily taxed) kinda thing works with income as well. Above a certain limit 100% tax makes all the sense in the world.
I believe /e/OS supports a broader range of devices, and it's also pretty great in my experience. The focus is on getting rid of google (replacing all services with MicroG and nextcloud integration) and blocking trackers while providing a smooth user experience, so it's security features are not as over the top as Graphene. It's still a huge freaking improvement over stock Android though, and I find it to be a joy to use.
On devices supported by the online installer it can be up an running in like 30 minutes, no technical skills required. :)
