You can blame both Google and Mozilla for ruining the chance to replace GIFs with APNG and WebP respectively. People were waiting the support of those for years in Chrome/Firefox, but their stubbornness already forced some image hosting sites to use video formats like WebM. At this point I am not sure WebP or APNG would become popular. But using proper image format for animation is a better solution , I think.
