Instead, I installed CalyxOS and have been using it over a year now and I'm very happy with it. Check it out.
You have to be aware that you give that person root when you use Graphene. All possible technical improvements aside this is a very big risk. He claimed he would step back after the video released, then called that a lie and continued with everything.
Calyx seems to be the best alternative right now without such a risk factor.
You just don't know what will happen is what I'm saying.
The "he has root" is also a reference to ubuntus shuttleworth.
You mean who tried to hijack the project in a very questionable direction, harming their users, he rather lighted the project on fire then let the users' security be compromised?
If anything, that is the greatest compliment you could give him.
Also, this is fud that he can push any kind of code, like you can easily check any part of the pipeline.
