The only way around the dystopia this will lead to is to constantly and relentlessly shame and even harass all those involved in helping create it. The scolding in the issue tracker of that wretched "project" shall flow like a river, until the spirit of those pursuing it breaks, and the effort is disbanded.
And once the corporate hydra has regrown its head, repeat. Hopefully, enough practise makes those fighting the dystopia effective enough to one day topple over sponsoring and enabling organisations as a whole, instead of only their little initiatives leading down that path.
Not a pretty thing, but necessary.
What we really need is for the collective browser vendors to refuse to implement this and, if Chrome pushes forward, to bring Google to court over it. Nothing short of legal intervention is going to help here.
