Two big issues for me that have kept me on Firefox despite being a huge cryptocurrency nerd:
1. The decision to base on Chromium is a bigger negative for me than any feature. We're all going to regret contributing to the One True Engine someday and it's going to be so painful to fix.
2. BAT is a pure money play. There's no inherent utility outside buying and spending. And Ethereum is nothing if not the biggest utility crypto out there. This is always one of those things in the Ethereum ecosystem where I point out that you didn't have to make yet another ERC-20 if your only play is money.
It's too late now, of course. But man, it would have been terrific to recommend a browser that blocked ads out of the box and wasn't part of the engine hegemony.
There is no meaningful technical criticism of Chromium that I have seen. All of the anti-engine folks’ main argument seems to be “it has the Google stink on it”, but I can’t see how that is relevant in an application explicitly designed to avoid their ad/tracking/cloud services. It’s just a renderer.
It’s just a renderer that calls home with hardcoded references to Google’s services. You can’t avoid Google if you use Chromium’s source code without patching it [1].
