Android paid app FLOSS?

hi /prog/
I'm planning dev apps for android market. I'm a FLOSS soft. user/hobbyist developer, in this case I want to make some $ (I can't eat freedom philosophy), my dilemma is if I want to earn some money I have not to release these apps as FLOSS, because I give up many of my rights, I only can earn money with distribution (as many of the future buyers of the app!!!).
In this case FLOSS doesn't works?
The only way is not to open source, proprietary software with EULA?

That's right. Except you suck at coding, so making a good proprietary app that will attract customers is out as well. I'd suggest a lowest-common-denominator app that either shows boobies or plays fart sounds. Maybe do both. No one will ever ask or care about the source code, I guarantee it!
