Not to mention that the dynamic would completely shift in terms of community contributions. If I submit a patch to a free project where the maintainers make nothing, I wouldn't even think of asking for anything in return (even if it is a project used by bigcorps, such as Redis or GHC). If I know that the maintainers get paid a full salary for maintaining the software, it becomes a much weirder thing to send them bugf…
"Sending them bugfixes for free" is both a benefit and a burden to an open source project. It takes maintainer time and effort to review the fix, test, make releases, etc, and that's a thankless job. When a company pushes their patches upstream, they're gaining a benefit for themselves (avoiding maintaining a fork), and potentially benefiting any other users who might be affected by the bug or want the same feature.…
Should OSS devs optimize for my (probably quite rare) use case? Probably not, but the feeling when making a patch for something that I like is still different when the maintainer runs it as a business compared to when they run it as a hobby.
(This is what the whole discussion seems to be about btw. Some people like to program in their free time as a hobby and other people would REALLY like guarantees about the software that cannot be made without losing the essential hobby-ness of it)
