Even at Google, most people find Gerrit to be pretty intimidating. It’s mostly only used for Chrome, Go, and Android and it’s far behind Google’s flagship review tool (Critique).
Gerrit is not a bad tool but it is somewhat hard to get used to if you have the more common GitHub-flavored git experience that most software engineers have these days.
I expect if the goal is to get the most vibrant contributor community possible the best thing would be to move to a GitHub-first workflow where Gerrit is supported as a backup. But there’s too much inertia for that to ever happen.
