That was like 5 years ago hehe (for animated pictures on major sites)

they do it for reduced memory footprint, pause/play, reduced size, better caching, hw decoding, partial decoding, fast first playthrough, higher possible bit depth for animations etc.
EDIT:
for regular pictures it needs to be an image format people can download and share

hevc in ISOBMFF (heic/heif) might turn out a good solution if windows users don't need to add support manually through the microsoft store and android switches to it.
then whatsapp could switch to it as well (with transcoding back to jpeg for older devices)
EDIT2:
at least Firefox finally added WEBp support (including animations) so it counts as an alternative (especially when they update their internal codec again)
