Apple's business model is more amenable to current law's obsession with "intellectual property". If the government grants you a monopoly over a market, it's not a crime to exert monopoly power over that market. Apple's argument is "we can sell iOS however we want", and this works because the US has the best copyright laws money can buy. We need to fix them.

Google, in contrast, started with a FOSS operating system and then added proprietary components provided under licensing terms deliberately intended to claw back your right to use the FOSS parts. For example, if you want to ship Google Play on a device, you can't also manufacture tablets for Amazon, because Fire OS is an "incompatible" Android fork. Google provided AOSP as Free Software and then secretly overrode that Freedom with the licensing terms for GMS.
