Google seems to love creating specifications that are terrible for the open web and it feels like they find a way to create a new one every few months. This time, we have come across some controversy caused by a new Web Environment Integrity spec that Google seems to be working on.
At this time, I could not find any official message from Google about this spec, so it is possible that it is just the work of some misguided engineer at the company that has no backing from higher up, but it seems to be work that has gone on for more than a year, and the resulting spec is so toxic to the open Web that at this point, Google needs to at least give some explanation as to how it could go so far.
