Redis developer and others complain that being a maintainer of a successful open source project is hard work. While I'm sure there are problems, it sounds a little like rich people complaining that they have a hard life.
A side plot is that apparently Linux distributions and users make changes and this is awaful for the maintainers. This I can't understand at all.
I would go as far as saying that if software is only ever modified by its own developers, it's not free software.
