Are you interested in knowing if you're having any success, or is this protesting for the sake of protesting?
I am interested in knowing if the boycott is directly impacting anything, but I do not believe the answer to that is something that will be revealed to us one way or the other.
I believe I have identified the source of our talking-past-one-another; your earlier comment about all that matters is results (or similar, not trying to misquote you). A flaw with results-oriented thinking is that in the absence of knowing the future, it can't tell us now in the present what the right course of action is or isn't.
Think of a sports league in which a team has to draft a rookie player. They do not know if this player will be the next great superstar, or a total bust. But, the draft is happening, so they can't "wait," they must use a process to pick one (simplified example; they could also trade the pick but that would also be using process-oriented thinking in that moment).
Also, it can be "protesting for the sake of protesting" as well; that is a valid means of expression here on the forum and not a bad thing as long as everyone remains relatively chill.
I'm not sure why boycotters apparently haven't posted much about this on other sites, unless it's because they don't want to sign up for other sites like social media. If the GOG forum is only a couple hundred "regulars", I'm not sure the message is meeting the majority of users.
This is probably the best suggestion in terms of how to improve the "process" (also was suggested to me by GR in this and other topics). That said, I have made the counterpoint in the past that GOG should - in terms of economic rationality - care what their customers think, so if people are on their forum complaining, this should in theory be "good enough" to get GOG to make changes, particularly if GOG verifies these individuals are among the longer-tenured and/or bigger-spending users. I also share nightcraw1er's concern, paraphrased, that a lot of people simply don't care about these issues. Think of a big youtuber...what is the "hook" for them to run a story on old GOG customers being upset? Their audience probably doesn't care thus it is unlikely it will get covered unless it is a passion project or somehow sponsored by GOG users themselves to get the person to make it.
