That post originates from AIOE.ORG.
Is my news provider relevant?

Perhaps it says something about the user?

"This site is designed as a last resort access way to USENET for those
who *can't* find a better option: please respect and support it."

I've known people who have used it because their ISP did not provide
Usenet access (either deliberately or because it was broken) and they
did not want to pay for Usenet access. Had they dug further they might
have found other options, but they did not.

If I would NOT get a revenue stream from my work, how could I
be motivated to do it?

Hmm - you mean kinda like Luke 10:25-37?

Or on a more mundane level, my wife's fundraising for our kids'
school?
I mean, they *could* have offered him a revenue for his work.
But not even one thought about doing that.

Perhaps thats because they don't have any money either?
I got even insults! "Correct that you MORON" etc.

You get that whether you're paid or not, unfortunately. :-(

Heck, I get that from my userbase even with stuff we bought from some
other bunch of bozos, such as those in Redmond, Mountain View or
wherever.
I think that the basic problem is that you are working for others
without ever being rewarded for it.

Agreed, but reward need not be financial. I know plenty of people who
actually get their kicks from solving problems and providing better
software.
I have never put people to work in my source code
as a project because I do not want to sell the work of other
people that contribute for free. This has limited the project,
but I do not see any way out

You could share the revenue stream? Its the traditional way to reward
staff....
