Hotlinking makes sense if you intend embedding inline an image to your site/forum/blog. Imgur still offers you this feature.
There is no (obvious) reason doing that when you are sharing a link to the image. Facebook/twitter dont allow you embedding images from external servers, imgur knows you are just linking to it, and redirects you to the image's page, as a well behavioured netizen should have done by themselves.
