> working on open source software is and can be a "real" job. the only difference to closed source software is that the source code is open - nothing else (simplified).
That is no small difference. In particular the business is completely different and if you want to make a living out of it, you should plan your job accordingly: find an employer that pays you to write the software, make a business around support for the software, open a twitch/YouTube channel and monetize it, etc., but asking people (or worse corporations) that have the right to use something for free to pay for it doesn't look to me like the best course of action.
> if you want your hair cut, pay the hairdresser. if you're interested in the continued development of the project, pay the author. it's as simple as that.
If you offer to cut the hair for free, you shouldn't complain that rich people don't pay for your services, and the "but everybody comes to me" is not a good enough reason, especially when being free is one of the motivations.
