All of Google's products are complementary products that create lock-in.

For instance both Chrome and Android have been created with the purpose of controlling the underlying platform that people use, in order for them to not be at the mercy of the other platform owners, like Apple or Microsoft. And it worked.

This is very obvious to anybody with an interest in how microeconomics works. For example this is why open source can exist in a world where people need to struggle to put food on the table. It's basic knowledge: complementary goods and services are meant to increase demand for your cash cows.

But alas good journalism is dead.
