alt Hacker NewsGoogle is actually kind of infamous for not using much in the way of OSS software.
The list of things I can think of is:
* Linux
* LLVM
* Webkit/Chrome (which they have done the majority of contributions to for a long time)
* Java & a little bit of Python

So if you subtract linux and LLVM and Webkit and Java, what is left of Google? Absolutely nothing. Well, a mostly empty, dysfunctional mono repo lacking the main dependencies.
For Linux / ChromeOS: GPU drivers benefit heavily: - Freedreno for Qualcomm - Panthor for Arm Mali
Lots of Linux contributions for Rust drivers
V8 (covered in Chrome), Angular, Dart, Golang, Kubernetes, Android (remember Android???)
Didn’t they open source Kubernetes (aka probably the biggest OSS project since Linux itself)
Oh, only Linux? /s
There's a whole lot more, check `third_party/` if you work at Google.
