In the beginning of the article, the author points out this set of techs as stuff that Apple does not support: {Service Worker, Web Components, Shadow DOM, Web Manifests}.
Well, you can go to caniuse.com, and see that for all of those (except Web Manifests, which doesn't show up), they are only well-supported by Chrome and Opera. Firefox usually has it disabled by default, and it's noticeably absent from IE.
I think the real issue here is something we might all find a little uncomfortable, and it's that the web isn't as important as it used to be, and Google is the only company really pushing it as a platform. Certainly, Microsoft may be repentant, but Microsoft either doesn't care to catch up, or they think it's not going to help them even the ground against Apple. And that doesn't deserve the title or the comments we're seeing here.
