True, for the most parts, and that's because they are resource constrained and Jolla is on the verge of bankruptcy. But all those features are not important to me. I care more about privacy (surveillance capitalism) than "security" (from state actors or malicious hackers). And seek diversity in software system by not supporting the duopoly of Android and ios, both from American BigTech. Sailfish OS ( https://sailfishos.org/ ) meets those requirement better. If Graphene OS becomes popular, it is likely to be surreptitiously gobbled up by one of the BigTech, just like Microsoft's investment in Cyanogenmod ... moreover, with Google slowly making Android more and more proprietary, I personally don't see a good future for GrapheneOS, and bet on Sailfish OS outlasting it.
