This is a Machine Learning product, I don't think anyone at Google, at least as part of this team, is trying to "get you" or destroy the open web or something. This isn't even a case of Google using something non-standard -- WebComponents is part of the standard, you can even see it in Mozilla's MDN [0]. Firefox, Safari, Edge, et al simply haven't implemented it yet (or landed in stable). Is that somehow also Chrome's fault?
Filing a bug report is good, but ranting on HN about how this is a sign of Google trying to steal the open Internet is at best unnecessary, and absolutely unreasonable.
Coincidently, I'm working on an application that uses complicated SVG with CSS animations, and I've spent a ton of time optimizing it. I've never tested it outside of Chrome before today. To my surprise, while everything works fast in Chrome, in Safari it's bearable, but in FF it's simply too laggy to use. Now, I probably won't ever get to fix the performance issues in FF and Safari, simply because I don't have the time. Am I also out there trying to destroy the open web? Maybe I'm just bad, not evil.
