The auto-start and auto-loop might or might not be wanted.
The main issue is just how freaking inefficiently huge gifs are for this use case : This whole thread, but also I was seeing an order of magnitude difference in a recent use-case I had, compared to mp4, which would have made sending the document by e-mail otherwise not viable.
(And imagine still living somewhere where a Mo of data doesn't have a negligible cost of transfer...)
I know that GIFs are very inefficient for what they're commonly used for, but your question was why people still use them. The fact they are “images” that are animated and loop is the whole point.
