The people that paid for that video to get it onto Akiba did support the studio with their wallets.
What about people in countries where these videos do not ship? How are they going to "support" the industry and acquire the discs? They can't even receive the videos. Maybe some of these companies should think about trying to expand outside of just Japan, if they're interested in gaining those precious extra profits. But alas, they don't bother, and barely even seem to go to the effort of offering proper English translations of their websites to encourage more business from the U.S. and Europe. MilkyCat and Asfur are examples of this lack of motivation. If Asfur wants to increase profits maybe they should join the 21st century and offer bluray, instead of stagnating in the 20th century with technology and video qulaity akin to 1997 (dvd).
If you're going to claim piracy caused a studio to shut down, what direct evidence can you provide to prove this? Also, how do you explain the fact that Asfur and Milky Cat are not closed, yet, still churn out videos regularly, despite people pirating their movies? Doesn't this contradict your claim that piracy shuts down studios? This seems to be a bit of selection bias on your part, which is not exactly a logical path to take. You select the event that coincides with your Pro-Increased-Industry-Profits viewpoint and then ignore the examples that do not fit your preconceived notion. Aren't Asfur and MilkyCat "indie" also? Yet, they still churn out content regularly.
Also, please provide the financial records and numbers that support your claim that Asfur is "in seriously bad financial situations." You either work in the industry and can back this up with numbers and valid information, or fabricated this purely out of thin air. Please don't bother providing unsubstantiated anecdotal evidence. (So and so told me something once...) Rational people require factual documented evidence, not heresay.
It seems pretty obvious you have a major role on this forum and it is to drum up profits for the porn industry. Are you a paid representative of the porn industry? You work "with many studios on a first-name basis" as you claimed. It's in your interest to increase profits as much as possible, but please stop acting like you're not here as a spokesman of the industry or as if you're just another one of the fans. You're here to criticize piracy and attempt to increase industry profits as much as possible.
You're on a forum that deals with a lot of file sharing, yet you seem to only speak out against file sharing. You've done this repeatedly in a multitude of threads, including the MilkyCat thread. Now you're here, bothering us again. Frankly, I don't think anyone cares for your lectures about "spending money." It comes off as condescending. Some people here do spend money, and some never would have anyway. You assume that downloading a movie freely has a completely negative effect on the industry, which is another flaw with your viewpoint. Downloading a movie freely may be the very thing that causes some people to actually purchase a movie in the future, or it may create a porn-purchasing fan. If a person sees what they like, they may buy something in the future. This happens with all media forms (someone gives you a book, you buy future books by the author, someone gives you a CD, you buy other albums or go to the concerts, etc.)
I'm sure this possibility eluded you, though, whilst you were typing your 25th lecture on the immorality of file sharing. Maybe in the future you can just keep a text document with all your pre-written lectures and copy/paste them to save yourself time.
