You mean Not just any porn, But Only Gay specific porn? (Then I get an idea which country they are from
BTW, it's not 'in Asia' as a whole, Japanese gay porn games are very advanced and well known across the globe. There's also South Korea and some other places.
BUT, That's totally understandable and reasonable what they did.
Why there are so much outrages and hates on this one? Is it cuz the game itself is bad?
Especially consider there are many games do 'tear NSFW away from the base, and sell them separately'.
