Population X = people who buys the program
Population Y = people who illegally copies the program
Population Y will not turn into population X, even if the programs can NOT be copied and MUST be bought
Reason: population Y is not really interested in the program, as stated in the second sentence.

If purchasing them were the only way to obtain them = cannot be copied illegally

B的意思是: 盗版程序不会被购买,即使购买是唯一得到盗版程序的途径.

问题是, most of the illegally copied programs would not be purchased by WHO?谁不会买啊？肯定盗版的人自己不会购买自己盗版的程序,那就是普通人不会购买了,但没有理由不买啊，文中说的是制作盗版的人对这个软件没兴趣啊．confuing!

谁能解释一下啊？

A = number of people who purchase the software
B = number of people who copy the software illegally but have no interest in buying it (much much larger than C)
C = number of people who copy the software illegally and have an interest in purchasing it if purchasing the software were the only way to obtain them (a very small number)
Number of total users = A + B + C
X = the money that the company can make now = A * (profit from each purchase of the software)

Now assume the only way to obtain the software is to purchase it
Y = the money that the company can make = (A + C) * (profit from each purchase of the software)

Z = the money that the company is now losing from illegal copies = X - Y = C * (profit from each purchase of the software)

Because C is small, Z is much smaller than "millions of dollars".
