All you will end up with, in the best case scenario that isn't even guaranteed to happen, is extremely mediocre games for which you will have the server executable along with the client.
Whether you like it or not, thanks to piracy and competition (and yes I've heard Gabe Newell's quote on piracy), server authoritative video games that are eventually turned off is a legitimate business strategy, and not even just for games. And no, "just release your source code then" is not a valid rule to enforce either.
If you like video games so much but don't like the terms of serivce and price, have you tried making your own? It has never been easier to do so, and there are freely usable code and art assets on hundreds of different platforms for you to attempt.
