When Facebook crawls your site, it uses the Canonical URL and links directly to this in all Facebook posts. This plugin prevents 
Facebook from seeing the Custom Canonical URL entered into the Yoast SEO plugin. This means it will always 
link to your own website, even if you’ve set the Canonical URL to another site.
