Chad, agreed to all. One other interesting aspect about going after the manufacturers instead of merely a distributor like Amazon - the manufacturers would probably aim back one more step - to the engineers of the standards for their products.
That would be Sony-Philips, leaders in the CD-Audio Disk format and the BluRay Disk Format.
Why not go after THOSE? Then, we could have Sony suing Sony.
That would indeed be the most justifiable action.
Amazon's been losing a lot of tax-cases in the USA, where they are forced to pay sales tax to those provinces where their warehousing operations work - where they 'sell from', so to speak. Maybe the EU courts smell lawsuit-blood in the water and think they can hurt Amazon while others are kicking it around.
But truly, there's only one difference between Amazon and the people (bigger distributors and the manufacturers themselves) that sell TO Amazon:
Amazon can supply addresses for individuals who receive those products.
Is Dollfuss still alive and kicking in Vienna, by the way?
