How does this study affect the holographic principle?

In a recent study (https://phys.org/news/2018-08-flaw-emergent-gravity.html) it has been discovered an important flaw in Emergent/Entropic Gravity because it has been discovered that holographic screens cannot behave according to thermodynamics...

But then, doesn't this also invalidate holographic principle? Since in holographic principle, entropy (information) from a bulk would be encoded on its boundary, and according to this study holographic screens would not behave according to thermodynamics, wouldn't holographic principle models also be affected by these results?

Here is the paper

Surfaces away from horizons are not thermodynamic
Zhi-Wei Wang & Samuel L. Braunstein

They only say "For surfaces away from horizons in the emergent gravity program the first law fails (except for spherically symmetric scenarios), thus undermining the key thermodynamic assumption of this program." In the text it appears that "emergent gravity program" refers to On the Origin of Gravity and the Laws of Newton. J. High Energy Phys. 2011, 29 (2011) which has nothing much to do with the holographic principle in general (eg, AdS/CFT or gauge/gravity duality).
