As the article points out, ChromeCast is an extremely locked down protocol. It's designed to bind your device and all its clients permanently into the Google ecosystem.
The real shame is that it had to exist in the first place and that DLNA was never adequate for this.

This does not pass the smell test. I can cast onto any of my Chromecasts using VLC and Catt[0] and while the former is limited to media, Catt lets me render websites just fine.
I believe Catt's author is on HN.
