clearly violate the letter and spirit of the definition of a music CD as per the Philips trademarks

The trademarks aren't important: to be allowed to place the Compact Disc logo on your product (whether player or disc) means you have to comply 100% with the Philips Red Book CD-A spec. This used to be based on a certification process: something that has quietly disappeared over the years as the product reached maturity. This was important - you couldn't make and market product without it. That's how Philips and Sony earned their early money on the technology.

Although Philips is now belatedly doing something about compliance, it's not very much. If they really wanted to, they could hit the companies placing "red herring" multiple directories on disk (to put off the CD-ROM drive based players) but I am pretty much certain that they are not going to do this since the current economic climate makes them sensitive to alienating their market. Unforch in this case, there's more royalty revenue from bulk disc sales than players - effectively meaning they don't want to piss off the big music companies by (legitimately) blocking production of non-compliant product that violates the conditions of the license granted to them by Philips to produce CDs.

A more effective long-term strategy for the punters (you and me) would be a mass-protest letter writing campaign to Philips NV in Eindhoven (the corporate headquarters) asking them to enforce the license conditions of licenses granted to BMG, EMI, et al. The net result could be that they are forced to remove the Compact Disc logo from their products. So what? Big deal! you say, and unforch - as Rob has already eloquently stated elsewhere - there aren't really enough tech-savvy consumers for this to make a difference. Only if Philips or Sony thought it worthwhile to force removal of non-compliant product from the market place would this make a difference. Inter-corporate wars would be far more effective than the big guns versus the Great Unwashed (us) 'cos we haven't the clout to fight back.

At least you'd be able to see which product is protected/non-compliant. Use your head, and vote with your feet - buy music only from manufacturers/distributors who don't employ copy protection. Economic power!
