Man that blog post has given me a lot to think about. What it basically boils down to is: if you want to sell stuff, better not act like a douche. I like that whole “we trust you to do the right thing” attitude, even when you know that people are going to take your basic tutorial on how to get your stuff for free and actually do it.
Why care? You’re not going to stop it anyhow. Better to focus on keeping a good name, which is to not appear like a money-grabbing corporation.
