Porn was never a central part of their works, theres no point in shoehorning in porn if it nerfs you by locking you to an audience that is dwindling in numbers.
Nitroplus being an outlier and sticking to their guns still making 18+ stuff is because theyre a weird company that prides itself on their weird, edgy shit and the 18+ rating lets them be as edgy as they want without console or TV anime restrictions (rumor has it theyve turned down multiple offers of a Soukou Akki Muramasa anime because they dont wanna budge on content). They're also financially very stable because Urobuchis non-eroge work and Sonico makes them money.
