As @Private_Prinny posted over in the GOTY thread, thought it more appropriate for my comment on his post over in this thread:
Alas, I agree, which is one of the reasons I’m getting a Switch, for portable gaming, this Christmas.
It does appear that Nintendo has swerved hard into the mobile microtransactions for their phone games, they’ve abandoned the Super Mario Run premium game model, and “progressed” from monetized Fire Emblem Heroes and Animal Crossing: Pocket Camp to the polished, non-Nintendo character based, Dragalia Lost. And, Nintendo is leveraging the monetization expertise of Cygames with Dragalia Lost, it seems. 
Similarly, Blizzard has released the premium Diablo III for Switch, but with phones it will be Diablo Immortal where they are using an outside studio, NetEase. Blizzard would not discuss their monetization plans for Diablo Immortal during their major BlizzCon announcement, but NetEase appears to have a poor reputation where monetization is concerned. And, Activision-Blizzard did not spend $5.9 billion for King, to transition their company away from Candy Crush monetization.
For a premium Diablo portable experience, looks like Switch is the best option.
Into the Breach being ported to Switch was good news, but last I heard it was not optimistic that it would make it to iOS or Android. Another data point that supports picking up a Switch for this Christmas, for premium portable gaming.
