A major component of NPD is it’s harm to the sufferer’s interpersonal relationships. I think the behaviors that contribute to this, though diagnostically and medically relevant, are generally deservedly stigmatized.

This is, of course, different from the armchair diagnosing someone with NPD just because they exhibit some of these behaviors, which I do think contributes significantly to the stigma of mental illness.

Ultimately, someone with NPD is more than their diagnosis and can certainly be capable of interpersonal relationships that are worthwhile to all parties involved.

I find it reminiscent to what Valve is doing with SteamOS and Proton today. That is, establishing a viable alternative to MS Windows through using Wine/Proton in order to not be reliant on a competitor for running their software.
