You won't stop gaming and won't stop buying games, GOG won't stop selling them and following the money, that can go both ways.
Thing is that it's both, both customers and GOG, but a change in customer behavior would change the industry entirely, while GOG's change of behavior eliminated a niche in the industry, a pocket for those who still cared. Terrible impact on those who do care, who did believe there could be something worth a damn here, but overall a mere tiny fraction of the impact a switch in customer behavior would have had.
Because these rotten practices exist because they generate the highest profits. Period. Otherwise they wouldn't hold. And they generate the highest profits because the most people fall for them. If they wouldn't, all this "machine" that just follows the money would change to follow the new course of said money, cater to whatever that large mass of customers would demand before paying them another cent.
On the other hand, GOG was something of a safe space for those who do care, regardless of what the rest were doing, of what the industry was. Them giving up on principles eliminated that pocket and left the, as you can see, small number of people who do care high and dry and hopeless again. But as long as most don't care and still fall for those practices, that pocket would have remained just a pocket.
So:
- Current situation: GOG, as the former leader of a revolution of the industry, gave in years ago, destroying this pocket it had created, probably dragging a few other small platforms that tried to squeeze their way into it down in the process and pretty much guaranteeing nobody else will try the same thing again with any notable success. Result: Rotten industry practices are emboldened, industry profits more, niche of customers who give a damn lose any hope they had of having something to support, all other customers see no improvement, and possibly even a worsening of the treatment they're subjected to. All customers lose, those who care lose the most and feel it most clearly.
- Previous situation: GOG had created a pocket from which the rotten industry practices were kept away, possibly encouraging a few others to try similar things on smaller levels and maybe making the bigger players consider making a few concessions here and there if they didn't inconvenience them too much. Result: Those who truly cared for something different had a place to gather in for a part of the products they were interested in, but the industry as a whole was still rotten, it still was the rotten practices that made the most money, most customers were still being badly taken advantage of and most products were still unattainable on acceptable terms. Customers who care have some partial gains, the others generally don't lose, but any improvements are questionable.
- Ideal situation: Customers no longer accept the industry's practices and no longer pay for any products that are not offered on terms that are in their advantage and not that of the sellers and rights holders. Result: Doesn't matter whether GOG or any other store still has values, because simply by following the money they'd all need to become ethical and respect the values of the customers, so the entire industry would improve in a way greatly benefiting customers, those who don't care just as much as those who do. All customers gain greatly, whether they even notice it or not.
