Oh .. long story .. the entire premise of google is to break the most impenetrable forts of centralization - take for example

- Internet Explorer with Chrome ( which btw is largely open source )

- iOS with Android ( again largely open)

- Mac And Windows - chromeOS ( which is essentially Linux)

- google FI to fight complete autonomy of AT&T and Verizon

- wearOS to counter watchOS .. practically free for the partners like Android

- wayMo to counter Tesla

- TPUs to counter nVidia GPUs

Google is makes centralized power into a binary choice and then opens up the floodgate for smaller players .. without google earth would be ..well still flat :-)

Besides the entire AI is based on transformers which is open source of google ..

Not even counting endless backend technologies.. like node ..
