There's a middle ground between FOSS and closed source, like having the source code open, and let power users compile it themselves, while keeping the copy-rights. Most code on the web works like this, as you can just right click and "view source", and easily debug and inspect. Does anyone have any experience with open sourcing, but with a restrictive (all rights reserved) license ? And would this be enough for people like the parent poster to run such a software ?
