Linux has working EAC. Any software not working on Linux is a Policy decision by the seller, not lacking features on the buyer.

Oh and rootkit level EAC? Expect that to go away on Windows too when MS finally gets sick of Crowdstrike and that ilk causing self inflicted Denial of Service attacks on whole economic sectors.

They can’t kick Crowdstrike out without permission from the EU.

It’s one of the bigger failures of antitrust enforcement I can think of

(I can think of much larger screw ups involving lack of antitrust enforcement, to be clear.)
