Thanks for explaining. Out of curiosity, does Microsoft have any external-facing GPL-licensed projects? Are there any restrictions to using (i.e. open sourcing something developed internally or forking something from outside MS) GPL-licensed projects? Specifically, would teams be able to get approval to fork GPL repos?

Git for Windows comes to mind. Teams can absolutely get approval for any open source license; however, for a GPL project, we'd have their open source legal team work with them to brief them on the license obligations and requirements, such as publishing code to https://3rdpartysource.microsoft.com/.

Interesting, so that's specifically for GPL-licensed projects? Or am I misunderstanding and you would have dev teams work with Legal for any open source licensed project?

Copyleft has more process, since we absolutely need our engineers to understand the obligations we have, and for some of us, it may be the first time we're being introduced to open source communities and licensing, so we have to do more education in the GPL case.

Our process revolves more about _using_ open source than forking specifically.

Whenever a build runs at the company, we have a detection task that identifies the open source that is used, storing an inventory. We evaluate the open source licenses for that inventory, and have automation depending on the license that will help inform a team that has taken a new dependency with specific legal obligations - could be to get business and legal approval for something, to take training and learn about copyleft software and licensing, or that they need to post third-party buildable source. We're also able to use that inventory to help with incident response and blast radius analysis.

To scale, we need to make sure that our guidance and policies are in front of people, but we know that engineers want to get work done (or will find a way around what we have in place), and so need to be efficient and straightforward.

Not all situations will require a business or legal approval. Our motto has been "eliminate, automate, delegate" - eliminate onerous bureaucracy and policies - automate licensing compliance and inventory and approvals - and delegate to business leaders and others when there's a need for humans to be involved.

Sorry for the long answer.
