From my understanding, they're claiming that the linear resistance-temperature curve with a slope of h-bar is evidence that the electrons are in something akin to a maximally entangled state.

Via the AdS-CFT correspondence, such a maximally entangled state is mapped to a black hole in AdS space in +1 dimensions.

With regards to cherrypicking, I don't think they're suggesting all HTSC demonstrate this behavior, but rather that the same principle is responsible for this phenomena in all materials in which it occurs.

I have certainly missed some details as I've never actually learned quantum field theory, so I'd appreciate someone more qualified correcting me.
