>When I worked at Google (2014-2018), it was easy to get permission to contribute to open source projects as long as the license was BSD, MIT, or Apache 2.0. The more restrictive licenses like GPL 2 or AGPL, I think Google either flat out denied or you had to do a lot more work to get permission.
Personally, I consider that a feature rather than a bug. There's a list of these licenses [1] and I make sure my software uses one of those on the list.
