Google. [23] Plus, Google pays Apple an estimated $3 billion per year just to

make Google Search the default search engine on iOS. [24] So you can see why

Google would prefer if people ran Google searches on Androids instead of

iPhones.

More Android users equals more money for Google, so it’s no surprise

Google is giving away Android for free.

Why open-source?

Android isn’t just free — it’s also open-source, [25] meaning that anyone can

make and distribute their own spin-offs of Android. [26] There’s a vibrant

community of developers making custom “flavors” of Android, like the

popular LineageOS (formerly known as CyanogenMod). [27] You can replace

your phone’s Android operating system with LineageOS to get improved

speed, security, and features. [28]

Android is literally open-source to the core; it’s built around the “kernel” of

the open-source operating system Linux, which is also used in some of the

world’s biggest supercomputers. [29] The kernel is a bit of software that lets

software talk to the device’s hardware, like by reading and writing files,

connecting to the keyboard and Wi-Fi, and so on. [30] A kernel is like a car’s

engine: the computer literally wouldn’t run without a kernel. Using this prebuilt,

open-source kernel saves Android developers a lot of work, [31] since the

Linux developers have been constantly improving their kernel since 1991. [32]

And Linux works on an incredible range of devices, from supercomputers to

video game consoles, [33] so by adopting Linux, Android automatically

became able to run on a vast variety of hardware.

Anyway, why did Google make Android open-source? For one, because

Android is open source, phone manufacturers get to customize the interface,

which helps their phones stand out. [34] That’s a good incentive for phone

makers to pick Android over another operating system.

Second, making Android open-source brings more people into the Android

and Google ecosystem. [35] Since Android is open-source, people who want to
