Always on drm has one downside that is has to work, people mostly accept launch issues with multiplayer games.
Launch problems with always on drm is entirely the company's problem as they could avoided it by dropping always on.
Yes criminal hackers using ddos to interrupt the servers for blackmail is the company fail.
Same with natural disasters.
It looks like its become less common, for it to work it has to be done real stuff on the server too, an just check if valid call is as easy to hack as anything else and this drives up cost an complexity.

On the other hand the problem with providing the game files on disc is that hackers will get access to the files far earlier often before discs are sent to stores.
Putting the game files (grapich and sound) and leaving out the few megabytes with program files would also avoid this problem.
