What you obviously are unable to understand that Il-2 and SoW:BoB are not mere pasttimes the guys at Maddox Games do in their freetime because they don't have anything better to do. These are commercial products which are by default a collection of trade-offs between commercially viable, financially acceptable and eligible from a gamer's POV. They have to earn money - they have a contract with Ubisoft and 1C to produce entertainment software which can be sold at a profit and so these two entities are calling the shots. And obviously the sounds fell through the priority grid for reasons none of us know.
Blaming the existance of the hack on Oleg is IMO simply a lame and transparent attempt at justifying the actions its makers. You don't like Maddox Games's development priorities? Tough, deal with it. All you can do is voting with your wallet but stop trying top justify some goon who needed the five minutes of internet glory by cracking files he shouldn't have poked his nose into. Nuff said ..
PS: And to suggest Maddox Games should support the hackers. Ridiculous, ludicrous and completely out of touch with reality. If I were a doc I'd prescribe a dose of reality.
