Almost every single company I've ever seen for 20+ years has open sourced their developer SDK examples. It literally makes no sense what so ever to do anything else.
This has nothing to do with what the OP was talking about which is open sourcing the core app.
The comment was about trending G Suite into open source.
You've got to start somewhere. It starts with developer samples, moves into tools, languages (Apps Script), then sub-products.
If you're asking for Google to open source it's products in one big blow, I don't think that will happen without smaller steps. I'm on the team that would probably best start the conversation of considering G Suite in open source. Would love to hear proposals.
I'd be truly excited if Google was prepared to state it had any intention to open source it's actual web apps. But everything I know about the company says that isn't even an option. What you open source is the same as most of the other things Google open sources: The things that funnel you into Google's proprietary services.
Even suggesting that Google Docs, Sheets, and Slides might be open source someday is as unbelievable as suggesting Google's considering open sourcing their search algorithm. But I'd love to be proven wrong.
You are reflecting very poorly on your employer because you are proving that they hired someone naive enough to think that he could try to open source G Suite.
There's an increasing amount of things you can do with G Suite, almost all our products have APIs and Apps Script libraries.
If there's something missing in our APIs, feel free to let us know.
