Actually I'm pretty sure WotC still owns the rights on the first print as the copyright doesn't expire for some time. Their pulling it from the website I belive was more of a discontinue as well as they sold off the product. The spread of the old product is actually benificial as I am interested in it only to get a taste till I can hold the final new product. Anyone who is not interested will not buy any form of the new one. Those who are will either buy the pdf, hardback, or both together. Most people still tend to want physical contact with their books and use the pdfs as only support. I own four different copies of True20 in pdf format and three forms of it in printed (one being a print of one of the pdfs, the second a limited print GR did, and then the final print) as an example. I know I don't represent everyone, but a lot of people are that way.
In trees I saw her,
Brightly like blossom blooming,
'Til shadows she left.
