firstpastthepost: They are a publicly traded company and they will base business decisions on what their investors want.
If by investors you mean greedy rich fucks who bought some papers and expect to become richer by sitting on these papers and doing nothing, then they probably want the company to rip off their customers as much as possible, selling the cheapest possible shit for the biggest possible price, exploiting people's addictions and vulnerabilities as much as possible with microtransactions, lootboxes etc.
If GOG decides to be ruled by those people, I'd say, fuck GOG. I don't know why the investors are being brought into these discussions like it's a sound and good argument, as if every good thing we have is not due to someone deciding to provide value to society and doing something for the actual customers, ignoring the investors' immorality and destructivity.
In an ideal world, an investor buying stocks of a company that advertises DRM-free should NOT expect that the company's business decision will be investor-oriented.
