I think the og:image meta tag is getting more popular to show previews of KYM's image pages, which point you to URLs like https://i.kym-cdn.com/photos/images/facebook/001/010/560/84f.gif. I don't know if it was useful to remove animation for certain services, but when people link to GIF photo pages on Discord everyone only sees a single frame.
