I think OSS have kind of problem with "too good" software. If your business is produce software and work as consulting company for it, software that is very good and easy to use is actively reducing your market, because frankly people don't need any help to use it. Take ES for example. Running big-ish cluster isn't that hard with a bit of googling and experimenting, so there is little reason to ever bother with support contract.
