And more competition in the h/w space? Common, you already have an insane amount of competition for Android phones, and even some of the biggest multinational don't give a shit about maintaining SW for their product beyond a few months, even for security purposes. The only think we can do is prescription to every people we know: ex. tell all your non technical friends to never buy e.g. a Samsung phone.
It's ridiculous, because Android is the worse ecosystem for security purposes. If you want to be somehow protected, you can stick to iPhones, or, in a funny way, Windows 10 Mobile.
That competition is only on the surface. For SoC, GPU, baseband, radios etc., you are stuck with Qualcomm. Or maybe Samsung's exynos, which isn't necessarily better.
And then on PC too, you pretty much only have competition on the surface; then it's Intel and AMD. Given how modern CPU are SOC (and chipsets are now paired with CPUs, and with no 3rd party licence anymore), you have almost all of what matter in your system (for system compat) there...
