> By the way, who decides what a legally recognized market is?

Primarily, the legal system, courts do. However, they always draw in expertise and considering that privacy experts don't agree on what a "privacy phone" should be, good luck defining that market when the market can't define itself. (Does it need secure boot or not? Hardened malloc? Tracker blocking? Sideloading or no sideloading? Allow background processes or not? Hardware Microphone disable switches or not? Some or all of the above?)

But then, even if there was a standard for a "privacy-preserving phone," is that market large enough to legally matter? Currently, judging by how many people are using GrapheneOS... No. Again, Apple has a monopoly on smartphones with Lightning Ports, but I don't think anybody cares about the "Smartphones with Lightning Ports" market.
