Sony fined by French court over DRM

I hear from Cedric Manara, via the CyberlawEU list that a French court of first instance has fined Sony UK and Sony France for illegal business practices in connection with DRM on proprietary ATRAC 3 format music files which they sell via a Connect website. The files only play on Sony equipment and the court held that the company had not made this clear to customers and that this tying practice was in breach of the French Consumer code, article L. 122-1.
