Honestly, I can sort of understand where he is coming from theoretically, but his take is also stupid.
The idea of the player being corrupted in a porn game is honestly great, but requires a shit ton of effort, testing, game design and other factors to achieve. Most of the times - it happens simply because the player gets inpatient.
I remember playing a RenPy Light Management game. When I started - I tried to play it safe, achieving the objective but not pushing too much. Not that I could, as scenes are locked behind some stats. So I took it slow - tried to gradually build it without risking too much. But... well, at some point I lost it, realized that I won't get any spice hot content that way any time soon and just started to not care about the female PC and began grinding the lewd stats to unlock new scenes, repeating content that gives stats, ignoring some of the mechanics the game has that do not benefit for lewd scenes e.t.c.
I got to the same phase with CoC2 as well, but it wasn't as good. In the beginning, I tried to stick to the characters I like, doing the thing I wouldn't mind doing. But eventually I sort of reached the point where I just stopped caring and excepted whatever the hell is going to happen simply because there is often no alternative way that isn't annoying. I remember I wanted to see Leoran Cait TF and spend like, 20 minutes trying to get Vari's encounter, running away for entire days to get her to show up, only to realize it's actually locked behind some time limit.
The only real corruption that happened is me no longer caring about roleplay, game's logic, or any sort of lack of meta gaming to see content. Can I justify my character running away for several hours? Sleeping several days in a room to see a specific dream? Especially in the game that tells you to hurry up and stop Kassyra as fast as possible? Not really. Sure, fuck me in the ass while I was going to safe zone because running away failed, I don't care anymore cause I ain't save-scumming because I got one corruption point.
And then we have him telling us it's our fault that Brint gets genderbend and we did it on purpose because we are corrupted as the players. Yeah, sure, that's a huge ass stretch that assumes waaaay to much, but believe what you want to believe.
