If a stranger drives through my neighborhood and asks "when are you going to plant begonias? I drive through here all the time but I want to see begonias", a fine response is "if you want to pay for some begonias, I'll plant them!"
The response is then the same.
Doesn't sound strange or entitled to me.

So not only is there not "begonias, open for everyone to view" sign in this case but there is a big sign saying "NO BEGONIAS GUARANTEED. IF YOU DON'T LIKE THE PLANTS WE CURRENTLY HAVE, THAT'S NOT OUR PROBLEM."
Maintainers are humans, and they're humans who deal with an insane amount of entitlement from unreasonable people. Their "I'm being exploited" nerves are a little oversensitive from repeated exposure, and that's understandable and forgivable.
Besides, the fact that the IBM employee followed up the way they did shows that Maximilian's "I'm being exploited" reaction was dead on—the person he was dealing with was not being reasonable. They responded to a very slight escalation in tone by throwing around dangerous words like "extortion". Would you have done that?
This goes double for Open Source projects. And the person asking is a leecher like here, I definitely wouldn’t commit to date either.
