The current context is within FOSS, however. And it has a widely known definition[1].
> If you're standing on a rug that you didn't pay for in any way, and you're nonetheless surprised and angry when the rug-owner eventually decides it is no longer practical for them to continue maintaining the rug for free, that's just entitlement.
So, let me get this straight. You're saying that because users didn't pay for the software, they're not allowed to be surprised and angry when they're forced to either continue using unmaintained versions, take over maintenance themselves or wait until someone from the community does, or pay up? And you're saying that paying for the software buys you these privileges?
So, essentially, if the author of cURL decided tomorrow that it's no longer "practical" for him to support ancient and obscure protocols like Gopher and Telnet for free, and he decided to put them up behind a paywall, that the people depending on these features don't have any right to be upset about it? And if they are, they're being entitled?
Or, from a social perspective, if the people making meals at a community kitchen decide that it's no longer "practical" for them to supply eating utensils for free, and start selling them at $10 a pop, that the people relying on those meals are being entitled if they're upset about this change, because they're not paying customers?
Don't you realize how hostile this is?
Forget about open source. This has nothing to do with licensing. The libre software philosophy is orthogonal to monetization practices, and every author can choose how they wish to make development sustainable, if at all. As I've said before[2], I'm in favor of F/LOSS projects having commercial tiers or subscriptions, as long as it's done fairly.
What I am arguing for is having basic decency to treat all users of your software with respect. The moment you decide that users not paying for your work are not worth listening to, that they're entitled, etc., and that your attention and respect can only be bought, you've corrupted the entire ideal of why we build freedom-respecting software in the first place.
The sad irony is that I'm 100% sure that most people arguing against this, including Datastar authors, rely on tools like `curl`, `grep`, and other libre software whose authors never have and never will pull these shenanigans. So they're quite happy to "leech off" other people's work, but not happy to let others do the same off theirs. This double standard is what's ruining open source, not entitled users.
I won't bother responding to the other comments, as they boil down to this same point. And I'm really repeating myself here, so feel free to talk amongst yourselves.
