I like the hardware kill switches too. It’s great to have a more free phone. Librem 5 is a nice step in that direction. I’d like my workstation desktop to simply have an icon down there with my phone number on it. We’re pretty much there. Admitttedly I use Graphene OS as well but I try to avoid it.
Taiwan manufactures something like 60% of the worlds semiconductors total…so everything from the most basic IC and something like 80% of the most advanced semiconductors on the planet. We have a very good reason to be concerned about China’s plans for it.
