achaye: My sentiments as well, the execs know they're losing sales, and we know that they know. What is important now is how can we get these companies to change? Unfortunately, I agree that the corporate suits do things that may not even favor shareholders if it favors themselves enough, and that is where we are at - they know DRM lowers sales (how much is another issue), but they do it anyway.
How many lost sales is enough so that the corporate execs can no longer ignore it, lest they are fine being booted out by shareholders? How many gamers have to stop buying from Steam and start supporting GOG and other DRM-free avenues? And why did Ubisoft release Rayman Origins COMPLETELY DRM-free from day one, but pack Rayman Legends with uPlay?
The only way to quantify exactly how much sales they are losing is to look at titles which are available on both DRM and DRM free platforms and what the percentages are for those? Outside of Witcher 3, what other titles do we know of comes even half as close of matching sales done on Steam? Most of the few indie devs that speak about sales numbers usually puts percentages somewhere around 85-90% in favor of Steam, with GoG maybe getting 5-7%. That's not significant enough to make any sort of change.
