> On the other hand, it's hard to imagine someone senior enough (in terms of experience, not years) who haven't ever hacked a FLOSS dependency to do something it originally didn't.

I can think of plenty of developers working in non-OSS (either internal/nonlicensed or proprietary licensed) shops who, even if they have and work with OSS dependencies, and even if they might hack on them for the sake of the projects they work on, have never, by (or at least as a result of the requirements of) employer policy, contributed a thing back.

Of course, that's because I've spent most of my career in that kind of environment, which is why I've got very little on my GitHub none of which has a direct relationship to my paid work.
