Lacking a feature that can just be disabled by the platform isn't really an advantage. I don't know why forcing things to be short by risk of large files is a good thing. Sharing gifs in image platforms is easier but the bandwidth skyrockets and is not an efficient way to communicate information. Platforms should be implimenting video support, not saying 'x platforms don't do it so we shouldnt'. The social media world has already solved the issue, why can't these sites.
