I'm only speaking in his mindset. I'm personally against the distribution of the links, but for me to remove the link would be a unfair for two reasons. First, there are people looking to find the free version. Normally this wouldn't suffice, but Kyrieu has also said he does not mind the distribution, though it hurts his sales. This would mean that if I were to remove them because I felt it was unfair to him, then I would only be satisfying my own opinion and anybody who shares it, while those who wanted a free version would be left out. In other words, I'd be acting alone if I were to delete the links on behalf of Kyrieu.
Am I indirectly advocating the piracy of his game? Somewhat, yes. But in the words of the creator, it'd be hypocritical of me to remove it on grounds of piracy. Imagine if I were to delete the links in the RPG Maker thread because every link there was essentially a pirated version of a purchasable game. Nobody would support my decision. Who would listen to me if I were to tell them to just go buy the game instead?
Does your opinion matter to some people? Sure. It made me double check whether my decision was correct. Does it matter to Coolguy? Not really. You aren't going to use the link. Does it matter to the people who are looking for a free link? Probably not, or they wouldn't be looking in the first place. Of course, you could always be that one post that convinces people to not pirate it, and hats off to you if it is, but it still doesn't mean that everybody is going to listen. There'll be people who want the free version, and if Kyrieu is alright with it, then I'm not going to deny those people what they want. Now if he were to NOT be okay with it, you'd better believe I'd delete the shit out of any link I find.
But yeah, get back on topic, etc.
