2) Service is not going to be able to easily attract users if they only accept bitcoin.
3) Why would someone pay money to pirate movies when they can just do it for free?
What's that line? "The truth is not a bulletproof vest."

We must have stopped talking about copyrights. Copyright is a system for promoting the progress of science and useful arts, according to my country's constitution (assuming we still care about that).
"promised share of the revenue"
So much for a market-based system where businesses are not "promised" revenue.
"the site is in the same boat as The Pirate Bay there"
On the forefront of using a revolutionary communication system to deliver creative works to people, despite constant attacks by greedy anachronistic businesses who failed to adapt to a changing market?
Promised by whom?
...because only a tiny minority of anarchists trust Bitcoin? Oh sure, you can point to a few "forward thinking" (also known as "gullible") businesses that accept it, but it is not even a blip on the radar of money. The overwhelming majority of black market drug sales in the USA are done in -- you guessed correctly -- US Dollars.
If you can convince me that (a) Bitcoin is something a court will recognize as money, and not require me to convert it to dollars first, (b) that I can repay any debt with it, including taxes, and (c) that it's value today will even remotely reflect its value tomorrow, then maybe I'll accept Bitcoin payments from you. Otherwise, you'll have to give me my country's currency, because frankly, nothing else is useful to me (unless I am in another country, in which case you'll have to give me that country's currency).
Let's put it this way: it doesn't take a bunch of people commenting about the exciting US Dollar or British Pound Sterling to keep those currencies valuable. How long do you think Bitcoin would last if people stopped playing it up as the next big thing?
