I have used asciidoc when I needed to generate PDFs for documentation.

You don't need any paid tools if you don't want them, I used a text editor and the terminal and source control.

I don't understand the hostility toward someone offering a product. It's fine that you don't need it, that doesn't mean someone else won't.

My worldview is there's a big market for WYSIWYG editors, and a big "market" for FOSS editors and tools, but not too much in between for simple text editing.

I can't think of many scenarios where someone does care about the backing format or explicitly wants to write raw asciidoc, but doesn't want to just use asciidoctor or other free CLI tools.
