Open source is good for clashes, and the latest is a vote by GNOME on whether to continue as a GNU project. (via) The triggering event appears to be a request from Richard Stallman for GNOME to not mention software that isn’t open source.
The long-term problem with something like that is that closed source software doesn’t go away if you ignore it. If people want to talk about the closed-source software they are using instead of open-source material, then you have to make the open-source software worth talking about. Programs don’t improve by beardo fiat. Plus, it only makes a difference as long as the producers are the consumers of the same software. (via)
