If you personally are willing to invest more, to dedicate attention and effort to every user/contributor/member of the opensource community you are maintaining, then that is great, and does not even conflict with the essay at all.

The only point is that all the time that you and other selfless maintainers are spending on their projects is not something that anyone is entitled to; it's a gift, not a duty.

To actually conflict witht the essay you would need to hold that any developer that ever publishes a piece of software is not only duty-bound to maintain it forever, but also to engage with every potential (crackpot) user or collaborator, and that's simply not a defensible perspective to me.
