Google does with all corporate sponsored projects. Most non-Google commiters just submitted simple bug fixes, most or all core maintainers are Google employees.

Google does with all corporate sponsored projects. Most non-Google commiters just submitted simple bug fixes, most or all core maintainers are Google employees. It's this way with every Google OSS project I know of. Guava, Angular, AMP, Chrome, Android, Tensorflow, gRPC. Sometimes they even de-facto take over existing projects, like Square's Dagger DI. Google has no open source governance model unlike Apache, the chaos that is Linux or rust, or even Java's JCP. Since a fork is so expensive to maintain over time, many of these projects are open source only in name. Google invests enough money to keep anyone from forking. Pennies for them compared to the huge marketshare they get for having massive "safe" OSS projects that companies won't worry about adopting.
