FFS guys he giving it away free, he can do what he wants, it his ball. Sometimes the people on this site make me worry for the future of humanity. Kids today...
If you actually read his posts he's doing 2 things.
1) Developing content for the rags version and he has provided a few bit of info on whats in the latest version (One of the girls has had a boob job, so that's an avenue you'll be able to go down). He post daily in the rags version, so is very much still active. The rags version will continue to be anti cheat as he wants it played in a certain way. In reality this doesn't matter as there is cheat version available in a matter of days anyway. He probably gets a kick out of coming up with new anti cheat measures in the same way people like Grey get a kick out of solving them.
2) Overseeing the development of an open source version. That will initially be a direct port of whats in the current build but will also allow others to write content for and be anti cheat free. Hes not doing the direct coding of the open source version he's got other people doing that.
The question he's trying to answer at the moment is whether the next release should be in Rags or whether he should just hold off and release everything in Ren'py having one version locked down and one version open source. He can't make that decision until play testing of the Ren'py version is finished.
Ps. Probably not going to respond to any comments on this cause flame wars are already 95% of the content on this site
