Does Amy Butler have a say in how we use her patterns?

I have always been confused about pattern designers saying what I can and can’t do with things I make from their patterns. I think this is such a murky area, that like the tags on mattresses, people are afraid to act because they don’t fully understand that ripping the damn tag off is fully within their rights after purchase. I’m intrigued by this site, www.tabberone.com, that outlines case law and what is really covered by copyright law. Here is a particularly interesting part about Amy Butler, who has been listed in their Hall of Shame.

So, does anyone have experience with this? It does seem that if I use her patterns to make stuff, I should be able to sell it. But I’m still afraid. Anyone else? And yet, I wouldn’t hesitate to sell something I made from a Burda or Simplicity pattern, because I almost always alter the pattern in some way.

I’m curious how other crafters feel about this.
