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."

Interesting. I do not agree with your summary of his post, in fact he goes so far as to say "an idea, really. Incredibly half-baked. Poke all the holes you want. It’s very unwrought and muy unripe."

So yes, we can laugh at the proposed mechanism but I feel the world would be a better place if we could funnel more resources to OSS creators rather than just take because that's an easier path.
