You really misunderstood what the key point is here. You couldn't be more way off base.

When anyone is away from an internet connection for more than 3 days or can't validate their installation.....the software ceases to function until it can re-authenticate. You are aware there is a single player mode/non-dynamic mission structure within DCS, you are aware not everyone has access to internet when they're away from home? For a game with a single player mode that doesn't require online connectivity to play it surely you can why a module that is part of the overall software package that ceases to function after 3 days without an internet connection is a bad idea....and especially so when that implementation is mentioned last minute and after some customers have already bought the product.

It's obviously pointless coming back with a reply every time that this DRM is the best thing since sliced bread......as long as you have got an internet connection and can re-authenticate after a period of time. Not everyone has that luxury for multiple reasons.
