GOG Galaxy isn't being released until August 31st..
While I agree that having D:OS delayed for non-KS backers until the end of August is a huge disappointment, we don't know whether this is GOG's or Larian's idea. Until more information is made available, it seems rather early to be casting blame.
However I would agree about the general mess that this has been for non-Steam users, including the need to email for a Steam-free disc version and the delay in offering GOG codes. GOG themselves have to share some of the blame (I'm still unable to download D:OS from them since the download links result in 404 errors) but this does suggest poor planning from Larian and a reluctance to accept there are customers (and backers) outside of Steam.
