From the opinion piece:
Last year, I pointed out how many big publishers came crawlin’ back to Steam after trying their own things: EA, Activision, Microsoft. This year, for the first time ever, two Blizzard games released on Steam: Overwatch and Diablo 4.
I wouldn’t call it fighting for a monopoly. It’s just that for the last decade people have been doing exactly what everyone keeps saying to do, voting with their wallet. Steam isn’t a clear market leader because people wanted it to be, it’s one because every competitor has not put in the effort to compete but rather chosen to be shitty towards the customer rather than be beneficial to the customer.
