You say you had to stop with the open source because you needed money. That has nothing to do with open source, and everything to do with the fact that you're not allowed to access the basic necessities of life if you don't allow yourself to be exploited for profit.
This is the underpinning of capitalism. Some people speculate that denying basic necessities is the only way to ensure that common people will be productive enough to make the wealthy people wealthier.
Funnily enough, in the eastern block almost everyone had to work. But as long as the wealthy people call themselves general secretary or commissar and talk about Marx it's all good, right?
Trouble is, the timing is never right to get out when there is always another payday just within reach.
These days I an happy to be paid to teach anyone anything but I have no interest in writing proprietary software anymore for any amount of money.
Everything I know and have built is because of FOSS and I owe that community my creations built on their work.
