I guess my point is that there's just too many netorare games and not enough netori or netorare(optional) games.
In general I'd agree. I think there's probably some more pragmatic reasons for this though. Porn games already have a massively reduced audience, further reduced by game genre and kinks, and as a type of porn, most things outside of the immediate porn tend towards more of an after thought when it comes to polishing them up.
So netorare games are already focused on the netorare, so when it comes time to making it optional it's little more than a token effort. The devs and writers never intended for you to avoid the NTR, so very little effort is put into the route to avoid it. Maybe you get some scenes, but they tend towards hyper-vanilla and few and far between as the game creators just never cared to spend the time and money on them. Conversely, games that aren't NTR focused and could reasonably include NTR as a penalty for certain actions tend not to because since they aren't NTR focused, people who the game is targeting will probably not find the NTR penalty enjoyable and that risks alienating them. So I'd wager the number of people who don't mind NTR enough they'd still enjoy a game where it's a penalty for losing are probably small enough that you aren't going to find a lot of creators who work on something like that.
Conversely, in netori, those likely tend to be rare as I'd guess a lot of the audience that would enjoy the game is more in it for the Corruption aspect, not the "stealing someone else's lover" aspect. Sure, they might enjoy doing that, but they're more interested in just the corruption aspect. So games that do netori are often games that could just as easily be Corruption/Trainer games if you're following the male PoV.
TL;DR: both netori and well fleshed out and sexy NTR avoidable are niche enough content that most people who are going to make the games either don't care enough about them to implement, or are focused on making money and so need to appeal to a broader audience that is likely happier to just leave them out altogether. Until the new tags are implemented and you can filter by "netori", probably best looking for "Corruption" games with "Male Protagonist" and "Trainer" games.
