Earlier quoted context omitted.
I assume that Critque is Grerrit with a bunch of Google-specific changes. Not even close. I have another comment where I get into some details, but, no, three's no overlap beyond the fact that Gerrit pulled some UI and workflow things from Critique (and Mondrian before that, the tool that predated Critique)
I dunno. I use gerrit frequently and nothing in this article surprised me. Aside from "ML-powered woo woo" I've seen and used everything bragged about in this article. Gerrit is awesome. I will never, ever go back to github.
They are two entirely separate codebases, built on two entirely different revision controls systems -- one open source, the other not -- with Gerrit inspired by Critique, not the other way around. Yes there are similarities be tween it and Critique. Because Googlers worked on both.
