 the security issues, but also in the process losing all the benefits of
 having an SVG in the first place.

 Yeah that seems correct, from what I can see they remove any script
 elements and then just convert to multiple PNGs of different sizes. They
 then serve the PNGs as the images on-site and just offer the SVG as a
 direct download from the media page.
