    “Windows 10 and Edge does’t even support WebP”?
    Edge SUPPORTS webp.

      Not what he said, read thoroughly. He said, neither Windows 10 or Edge browser supported .webp when they were initially released. I think the author was trying to give the reader the idea of how NEW this technology is, and how it’s support is building, but still is not all the way there. Though, I can admit, his claim is quickly becoming outdated.
