I made the argument on IRC the other day (or was it here? I'm too boomer to remember) about how how those who complain about a 900 KiB GIF file because "think of the mobile users and their crappy data limits" would happily insert a 14 MiB MP4 file that's on autoplay, has no controls (so you can't stop it), and without audio into their already way too bloated "mobile friendly" websoyte filled with ads, trackers, and other unnecessary JS/CSS cruft.
