You fail to get it, YES Blink indeed is in fact dangerous because its controlled by Google and they dictate what they allow and what will be next things in the Browser and basically force everyone else to follow up with features they implement. They have a way to big control over browsers with the large market share they have. It has very little to do with with privacy. I use Brave myself. Using Blink as rendering option is cool and its cool that is open source but it does not change the control Google has over browsers. People could fork it of they disagree with things they do but if they are not as big as Apple the fork would disappear into meaningless and would never even come close to somehow influence and web standards ...

This is far worse than the "you can just re-skin safari" on iOS nonsense. Blink is just another tool to force cash cow $$updates$$ onto users they didn't want or need.
