OSS have benefited from Google Summer of Code, Google has released many fundamental libraries as OSS such as Guava for Java, Abseil for C++, etc. Many have criticized that Google never made money of a lot of its innovations, and instead had others build their own based on Google's shared information (Hadoop, and later all nosql databases, for a quick example; Docker came to be from open source innovations that Google put into Linux for their own container system). Even as Google has begun monetizing, they still open source core parts of their products (such as Kubernetes) for their benefit.
