What a garbage article lol. The only two arguments I can pick out are 1. Old steam games haven’t been updated to work on macOS and 2. Some games require 3rd party launchers. I think the author was just angry that his mac dropped support for a 20 year old game.
The only thing keeping me on windows is the Nvidia GPU in my laptop. If Linux got actual dynamic GPU switching support I would delete windows and never look back.
