Let's say WEI is all good - we trust Google and all of the people involved and it gets passed and implemented. Later on, by gradually changing it, it becomes all of what we feared it will become. How do we get back at that point? Can we even get back to a state before it? How would we fight against it? Do we just stop surfing the web as way of protest? Obviously that won't work.
There's an immense power disbalance about this and any privacy limiting or freedom limiting features. Once they go through, there's no coming back from it.
