I don’t understand why Google didn’t just made Android closed source. They would’ve made custom roms impossible and therefore more able to control and spy on it’s users. Why did Google made Android open source, while Microsoft’s Windows is still closed source to this day?
That’s a nice dream, but it’s just that - your dream. Even RISC-V runs on existing ARM cores. Unless you have a few spare billions to build competitive fab, nothing will change.
