"....This is actually a really sad day, as along with Steam, GOG was one of the best places to pick up older games without having to shell out a small fortune on eBay, or fiddle around for hours trying to get a game designed for Windows 95 to work on XP."
The above paragraph from the article is part of the reason GOG went down. Steam always being mentioned in the same breath every time GOG is mentioned, and the truth being hidden to help Steam over GOG because Steam is American and GOG is European.
In the above quote for example, it implies that Steam games are also DRM free and tweaked to work on XP, Vista, etc. This is not true. Only GOG did that, and here we are seeing Steam promoted as doing something they don't. This happens all the time. GOG was not at all like Steam, other than you paid for a game and downloaded it! If GOG goes, you watch how quick prices will go up on the retro games Steam sells!
I think what happened is that GOG ran out of companies willing to let GOG sell their games DRM free. They knew if they wanted to sign up more titles they would need some sort of DRM after all. this is what GOG 2.0 will be, higher prices and some form of DRM.....
