I agree that the Web Components debacle represents bad behavior on the part of the Chrome team, but this title ("Chrome is the new IE") is extremely editorialized in a way that the guidelines explicitly ask you not to do.

> 1. design a flawed API (it's fine! APIs are hard)

> 2. ship it in the most-used browser, despite objections

> 3. get cross-browser working group to fix the API

> 4. oops, too late, that would break the web

Is this about DOMParser?

(Which upon a parse error generates a DOM tree with an 'error document' instead of returning null or throwing an exception...)

It's about Constructable Stylesheets. The entire discussion is here: https://github.com/WICG/construct-stylesheets/issues/45

TL;DR

- Chrome proposes a new feature

- There's no consensus on the API among implementors. Chrome team themselves agree the API needs improvement

- Chrome ships the feature as is

- The standards body proposes a different API

- Chrome team says that nope, the feature that the implemented, that no one agreed on, and that they shipped is the standard and they will not change it
