Yeah, it's a continuum: from an explicit "outside contributions not welcome" to "we'll accept more or less any contribution with little review" (zeromq, under the current maintainer, I know is an example of the latter when orginally it was much more the former). Most projects are somewhere in between (linux I'd say is relatively hostile to new contributions), and the extremes are rarer.
