&gt; They ask for bug fixes and feature improvements that would take me six months (or more) of full time work. They don&#x27;t offer to pay (or then even balk at the thought), they just keep saying &quot;you should support us for free because it&#x27;s open source.&quot;<p>If you ever do business with corporations, you will get used to the fact, that they will for the moon and expect it for free. It is your task to tell them, what you expect to be paid and stick to it. They won&#x27;t volunteer any money they don&#x27;t have to, and will use any excuse that will make it possible (the procurement bonuses depend on money saved). It&#x27;s up to you to not accept that excuse.
