It is all a gimmick but as long as people are switching to a chromium based browser and not Firefox I'm happy. With that said, I don't know how anyone would trust a small team to build them a secure and safe browser. Chrome is so battle tested at this point and Google puts a lot of resources in maintaining it, they stand to lose a lot more given their scale.
And so you throw in your lot with the strongest warlord on the block, and then they turn your shelter into a prison.
