Did you even read the article? This is a matter of limiting the number of times a licensed user can authenticate their copy of the game within a day (based on hardware/software IDs).

It's to stop pirates from using one a legit activation 'key' to provide the game to others. Which is funny because they've found a way to extract the denuvo 'key' from a demo and spoof full game denuvo access for other games.
