You should be able to share source, allow individuals to use and modify your work and build a community around that work without worrying that same work will be co-opted by an entity seeking to undermine the effort you and your community have done for years, by slapping a different name on it and hosting it, competing directly against you with your own work as a business.
I'm fine if "Open Source" can't be used to describe these projects which are working with imperfect situations and looking to protect themselves while still providing their software with generally good intentions, but by the same token I then hope the software community will come up with a new good name for these type of projects, it becomes the common name, and the dogmatic definition of "Open Source" fades into the relative obscurity I think it deserves from being so divorced from reality.
