I haven't been up to date on all of this in the community, but here's my two cents based on a little reading I have done on the regional pricing controversy.
I feel for the people that feel used because you did a lot of free promotional and service work on GOG.com's behalf. I would feel betrayed too if I did that. I just don't feel that way because I quit doing that sort of thing for anyone a long time ago. If people asked me where to get a digital PC game, I recommended this store because it is my favorite but I never tried to persuade anyone to buy here.
I treat this store like a store. I'm not loyal to it, I'm loyal to what I value. They just happen to offer what I subjectively value the most compared to other stores in my cost-benefit analysis. My confidence is high here. They have to offer me something I want for me to give them something they want, and as of right now, what I value most (not having to ask a third party when, where, or how I can install or play a damn game) hasn't changed here. My price also isn't going to change, but I can definitely understand why people are upset if their price is affected by this change. I am a little worried about what the signs appear to be pointing at in the future if they decide they need "features" like region locks too, but I'll crack open a bottle of whiskey and drown my sorrows if and when that day comes, not now based on speculation. For now, I'll just make sure my games are all backed up in case that comes.
Right now my main concern is that the price of AoW 3 is way too high for a digital game and so will be the price of the digital version of the The Witcher 3. I don't value any DRM-free digital game more than $20, no matter how bad my itch might be to play a new game, and if I can control my itch, I will pay much less for a digital game. If the retail version of TW 3 is also DRM-free, then yeah, maybe I'll spend more than $20 for the box version.
In my ideal world, the retail versions and digital versions could do what they do best and coexist. Digital could be cheap and retail could offer goodies like the big boxes used to offer and charge what they need to provide that service. Sure, retailers would probably see a drop in sales so that instead of purchasing 1000 units they might have to purchase 500 instead but they have to do business things like economic calculation to determine if it is worth it to them. Not everyone will just automatically go digital because it's cheaper. Price isn't the only thing people value.
Even if digital cuts into retail so much that many retailers have to close shop or become a small niche, then that is what the market demands anyway and a successful business will either go where the demand is or successfully persuade people why their product is superior. Right now, it's kind of a Sophie's Choice anyway since most boxed games are just Steam keys.
Lastly, I've seen people concerned that this move points toward a Steam-like store (I'll use Steam since it is the most well known). While this is certainly possible, I don't think it would be a wise choice. Most customers value these stores for different reasons. I don't claim to have numbers (but neither does anyone else arguing differently), but I don't think it is a zero-sum game. Some people here were pirating games before they became customers, some (like me) just quit playing PC games altogether.
My point is that we all weren't Steam customers before GOG.com existed. Those that were and still are Steam customers because they value what Steam offers are going to continue buying Steam games unless GOG.com can do what Steam does better, and I don't believe they are in a position to do that. If you feel like what GOG.com offers is already better then it's because this store is NOT like Steam. Those of us who were not and are not Steam customers will not buy Steam games over GOG.com games unless Steam offers us something that we value more, which for most of us would be 100% DRM-free installers so we could browse titles there with confidence. We anti-DRM customers would go back to pirating or lose interest entirely in PC gaming if GOG.com moves in a Steam-like direction.
One store's folly is another store's opportunity though too, so maybe we'd all just give other stores like DotEmu or Humble Bundle more business instead. I don't like those installers or zipped folders as much though but if there's more business flowing they could fix that.
