I often wonder how secure these open source projects actually are. I'm curious about using Waydroid in SteamOS, but it looks like it only runs LineageOS (apparently a derivative of CyanogenMod).
I know that people claim that open source is more secure because anyone can audit it, but I wonder how closely its security actually interrogated. Seems like it could be a massive instance of the bystander effect.
All of it gives me a bias towards using official sources from companies like Apple and Google, who presumably hire the talent and institute the processes to do things right. And in any case, having years/decades of popularity is its own form of security. You know anyone who cares has already taken shots at Android and iOS, and they're still standing.

I was involved in addressing in issues identified in the first one in 2015. It was a great experience, much more thorough than the usual "numerous static analysers and a 100 page PDF full of false positives that you often receive.
