A big problem with GrapheneOS is the fact it only officially supports Google phones. Google is apparently incapable of selling those things globally, limiting availability.

There's also the fact hardware remote attestation is creeping into the Android ecosystem. There's absolutely no way to daily drive something like GrapheneOS if essential services such as banks and messaging services start discriminating against you on the basis of it. Aw shucks looks like your phone has been tampered with so we're just gonna deny you access to your account, try again later on a corporation owned phone.

GrapheneOS is amazing from a security and privacy perspective but it doesn't matter. The corporations will not tolerate it because it works against their interests. They will ban you from their services for using it. Unlike Google and Apple, they have no leverage with which to force the corporations to accept terms unfavorable to them.
