That was my point. GP mentioned trademarks for no reason and I said that the DMCA is a copyright law (that's what the C stands for), and that trademark law is irrelevant to this discussion. I also agree that even if trademarks mattered in this case, it still wouldn't be infringement.

On the other hand, it looks like it was an improper use of the DMCA because they're claiming that EasyList is an anti-circumvention tool (effectively arguing that it breaks DRM).
