Open source code can be charged money for, if the author so chooses, and there are lots of companies with this business model. Even setting that aside, I never proposed that (of course I and many others use open source code freely), but I was just commenting (generally, not necessarily towards you) on how much entitlement there usually is in the open source community, as if it's not enough to make something for free but that people even complain if the creators ask money for it.
Thanks for the clarification. I have no problem paying money to support open source development, or to pay for support or sponsor open source features I need, etc. I don't use non-open source code for anything critical in my business, and avoid it whenever possible even outside of critical functions. That includes proprietary extensions to open source cores.
I don't mean to sound entitled, I always want to express gratitude to developers for contributing to open source. But I will say that I would never pay for proprietary features- not because I don't want to pay, but because I want open source features, and I am willing to pay for open source features.
True, I definitely don't use non open source stuff for my business either, on the code side, but I definitely do use user land applications that aren't open source, for example Google sheets or QuickBooks for accounting, because user land applications are not necessarily something that there are good alternatives for that are open source; I'd never use OpenOffice over Google sheets.
