Disadvantages that could drive away subscribers:
- Custom domains created for own branding, not Obsidian Publish.
- Impossible to disable on a paid product.
- Seen in search engines results almost implying the content is from Obsidian Publish.
Should be at least optional, with a chance to disable it.
This prevents serious self-publishers with custom domains from using Publish.
Ghost, Wordpress, or any other major publishing platform does not inject their brand in every page title of a paid product.
