From the article
Microsoft has officially announced its intent to move security measures out of the kernel, following the Crowdstrike disaster a few short months ago. The removal of kernel access for security solutions would likely revolutionise running Windows games on the Steam Deck and other Linux systems.
Unfortunately most Battlefield games worked fine with Wine/Proton for years since EA used server side AC, so they already have our money.
I got battlefield 5 and explicitly rebought it for Steam to play on the Deck. Like a year later they rugpulled Linux support because 2042 has done so badly that they had to start maintaining their old games again.
