The free software as a passion project idea became untenable long ago. It works for UNIX style utilities where the project stays small and changes can be managed by one person but breaks down on large projects.
As a user, try to get a feature added or bugfix merged. Its a weeks or sometimes months/years long back and forth trying to get the bikeshedding correct.
As a maintainer, spend time reading and responding to bug reports which are all unrelated to the project. Deal with a few pull requests that don't quite fit the project, but might with more polish. Take a month off and wait for the inevitable "is this being maintained?" Issues reports.
I contribute back changes because I want those features but don't want to maintain a longterm fork of the project. When they're rejected or ignored its demoralizing. I can tell myself "This is the way of open source" but sometimes I just search for another project that better fits my needs rather than trying to work on the one I submitted changes to.
That is the happy path. The sad path of this is how many people look at the aforementioned problems and never bother to submit a pull request because it's too much trouble? Git removed most of the technical friction of contributing, but there is still huge social friction.
Long story short: the man pages maintainer deserves something for all the "work" part of maintaining. He can continue to not be paid for the passion part.
Just want to point out that it absolutely is possible to train an AI that will keep track of its sources for inspiration and can attribute those when it makes a response.
Meaning creators could be compensated for their parts of AI generated stuff, if anyone wanted to.
