But I also understand that the true beauty of open source is the entitlement of free work from devs on a project receiving less than 8 euros a month from donations.
Someone posted the project to Hacker News. A commenter pointed out that they didn't put the supported platforms on their website. That has nothing to do with "entitlement of free work". If the devs don't want anyone else discussing their work, they have every right to keep it private. If it gets posted to HN, it will be discussed.

This is entitlement to free work. Raising an issue is much more reasonable than an HN user submitting a change on behalf of another random HN user. I do understand that the OP wasn't asking for someone to do this for them, though, and not displaying supported OSes is a totally valid critique.
