Pop science doesn't vindicate textbook science which still discourages high amounts of saturated fat.

And the Massai (and Inuit) referred to in your link are hardly good examples. They have short lifespans (as low as in the 40s), suffer from atherosclerosis and thickening of the arteries. The Inuit are also not long lived and have a high rate of osteoporosis. These groups' "adaptation" to a high protein meat diet is hardly desirable. They are forced to eat a high meat diet out of circumstances, not as a chosen optimal way of life.
