I'm focussing on the claim made by OP which is contrary to what is commonly reported (I provided the paste from the news report). He stated "It explains why porn is mostly made in low income regions like Eastern Europe and South-East Asia."
Do you believe OP's claim to be accurate? Could you clarify what evidence you used to form that belief?
Nevertheless, there are a lot of Eastern European porn actresses, and also a lot of videos filmed there, because well, that's where the actresses live! It seems like a combination of bad economies and attractive[1] people - there's presumably less Swedish porn because Swedes can get rich[2] by working a "normal" job, and there's less porn from (exercice for the reader: insert a country here) because the average porn viewer wouldn't find people from there arousing.
[1] Attractive for the average porn viewer.
[2] Rich in the sense of being able to afford a lifestyle, e.g. brand name stuff and the newest iPhone - an average Swede can probably afford those things with a few months' worth of savings, but an average Romanian would have to save a lot longer.
I did not attempt a rebuttal. I merely pasted a paragraph from a news article to point out that his claim doesn't seem to match up with what is commonly reported. Is his claim based on data? Or how about your claims? Or are both based on what categories of pornography and porn actresses viewers watch?
How is "I merely pasted a paragraph from a news article to point out that his claim doesn't seem to match up with what is commonly reported." not an attempt of a rebuttal? And your counter-claim (which countries host domains) doesn't fit his claim of "in which countries are porn produced"?
It'd be like him saying iPhones are made in China and you quoting an article that says he's wrong because the majority of iPhones are sold in the US.
I don't look forward to be even more confused.
There's a disconnect between where the models come from, and where the money goes.
