True, but I take it as lazy programming. If it’s a file then download if it’s a video depending on your browser and any extensions/plugins it would essentially stream it instead of download. But true it’s still sus.
An adblock doesn't necessarily help here. Those work by blocking pictures from being loaded from domains that usually serve ads. Here, they're likely hosting the download link images on their own server, but they'll send you someplace you don't want to go.
