Ok, just sell it. That's something that cares only to you but I'm going to tell you something: remember that you are not paying for development. Devs are free to stop, continue or delegate the development of their Roms when they want and we, users, have to respect that.
If you don't like that, that's up to you but it's very mean to devs when a person complains in the way you do.
Btw, I'm using custom ROMs since mi first Android: an htc magic, so I know the value of what devs do and I don't find right to complain for something that you are receiving completely free.
