I think people should have to lurk and contribute a little before just advertising.

I don’t think we should promote closed-source apps on here at all, at least not in it’s own post. For exampke, many people here talk about Symfonium when mentioning their music client that they use to listen to their selfhosted music, and that app is not FOSS at all.

If an app is mostly open with some proprietary bits, then we can discuss. I’m perfectly fine with fully OSS apps that aren’t free, as the devs do deserve to be paid. As gnu.org states, Free means “Freedom” not “Free beer.” While I typically only use “free beer” type FOSS apps, I do occasionally donate to ones I love/use often, but we know that devs struggle to keep their projects afloat.
