Strictly speaking, you're right. I seriously doubt that CDSM would have legal grounds for a trademark infringement suit just for the mention of their name. That being said, the reason I've advocated being a little more circumspect with regards to CDSM and EveryNote is that IMSLP does present a direct challenge to their business model - which consists of selling scans of public domain scores. While it's quite clear that a PDF generated from scans of a public domain score is not protected as a computer program - that does not prevent someone from dragging IMSLP to court over the issue.
After all, why on earth would anyone pay $15.00 for a CD-R of PDFs of scanned music scores when you can download the identical pieces from IMSLP at no charge? At least some of the print publishers I deal with view IMSLP differently: If someone download all 400+ pages of Massenet's full score for Werther, they then have to figure out a way to a) print it onto a size and quality of paper they can use (usually 8.5 x 11 in the US); b) bind all those loose pages in such a way that they can be used, etc. For many folks acquainted with the process of dealing with this type of thing, it's often a real bargain to simply go to Sheet Music Plus or Amazon and purchase a nicely printed and bound copy for $50.00 (or whatever).
I expect that IMSLP has now gotten so huge that it's unlikely that CDSM, EveryNote, et al are unaware of what's going on here. However, since we've already received threats from one major European publisher, I suppose we shouldn't be thumbing our noses at other parties who might be inclined to hire legal guns to attempt to shut the site down.
