The sense of entitlement is strong in these comments. If you haven’t built or maintained OSS I’m wondering why your opinion matters [edit: that's harshly worded I could have been more nuanced, hopefully the point is taken and it is a question]. There’s also the take that “this is fine” vs considering that the state of OSS things could be a LOT better with higher quality and more choices if we fed the beast properly.
I don't see any entitlement at all, in fact it's the opposite.
The article: "I expect open source maintainers to maintain their codebases and add new features. I have unilaterally decided that $1/package is a suitable amount, universally applicable to all packages and maintainers." <--- this is entitlement
The comments here: "Open source maintainers don't owe you shit."
