I'm not saying you said he was a massive fan. I'm using his own words which he sent me in a DM a couple days ago when we were talking about something NTR-related (we've also discussed this in the past).
Haha well, if we're going to get pedantic, I didn't say that the dev's opinions and tastes hadn't changed. I simply said they had, early on, said they liked it. I linked to the quote to show that was true.
Regardless of the pedantry, the fact remains that many events and scenes are set up specifically with the primary purpose of creating an opportunity for NTR and for which a non-NTR alternative is clearly a secondary path or even an afterthought. That's the part that helps the person asking how NTR features in the game understand what they are getting into.
However, just like the Devs, the broad 'NTR' label is rather vague at times. One
could argue that there isn't really any full NTR, even with the option on, simply because there is no path (yet) where any girl is actually your girlfriend, or has committed to any kind of monogamous relationship. As far as I have played, you're kind of just fuck-buddies or FWB with any of the girls you can romance.
