I was seriously thinking of contributing to open source this past week when I started going over all the articles I've read from open source authors about entitled users and wealthy companies that don't donate but make profits off the projects. It's beco0me clear to me that large corporations like Microsoft have jumped into open source whole heartedly in a big part because they get tons of free labor. Not only that, I had a bad experience contributing to an open source project in which the author snidely told me I should have searched the code base because the bug was fixed when it wasn't, closed my bug report out and denied my pull request. So it seems to me a negative deal situation on both fronts. I'm know there are great open source projects, but I'll need to be very selective about them.
