Corporate open-source (Open Source) is done for free labor and PR, it shouldn't be bonus points for any company that does it, unless they commit to it and pay their contributors, have no CLAs that allow them to relicense the work, or adopt practices and licenses that are clearly more in line with the actual spirit of free software. Real free software that should be considered a public good is produced by people, for people.

There are sometimes well meaning people in corporations that do their best to at least get something out there and kudos to them, but corporations running Open Source projects should receive no goodwill for it, it's basically a scam.
