There is a very reasonable expectation of this changing at some point in the future.
A lot of gamers seem to be happy with versions that have these symbols replaced and everyone else simply imports them (which is as simple as ordering from amazon.co.uk instead of amazon.de). Publishers have simply no incentive to pursue this and because violence in games can be censored, publishers censor a lot of games on their own already anyway. I would not be surprised to learn that there are companies even profiting from the current situation.
(Even though, imo, the dude outright lies by stating that their interpretation of the law is what the law factually says.)
Also, do note that i said at some point in the future.
Nevertheless to my understanding if a publisher were to get a game censored by the OLJB due to forbidden symbols, the publisher could go to court and I think they would have a decent chance at winning such a case.
Are you agreeing with the law exactly as it is written? (I am.) Are you agreeing with the interpretation of the law as it applies to computer games? (I don't.) Do you think computer games should never be allowed to contain historical symbols of forbidden groups? (I don't.) Do you think computer games should be allowed the usage if the usage serves the art? (I do.)
It depends on the context. The computer game should not facilitate identification with Nazism (e.g. by the player flying that flag in a RTS or being a member of it in an FPS) or downplay the disastrous results of Nazism. So potentially I would be okay with a Wolfenstein-like game where the player operates strictly against these powers/symbols, but doing this consequently in online multi-player games seems difficult.
Exactly that is my point. :)
