I dislike companies which generate their revenue by marketing only, without having good-quality products.

AOL Time Warner is a good example. If you hear their CEO speaking, he always talks about "brands". No surprise, because that's all he's got to manage. This company got large by good (and unconventional) marketing (just like Microsoft), and that's all they can do.

Occasionally, they suck up another company with a good product, but they almost always manage to make it a failure. E.g.

• CompuServe had a good strategy to make itself fit for the Internet, yet has been neglected.
• ICQ is probably still number one in the instant messaging market, and it is owned by AOL, but AOL acts as if ICQ would not exist and pushes AIM on all fronts. They are lucky that AOL didn't close them, like CNET did with GameCenter (the best online game review magazine I knew) in favor of the incredibly dumber GameSpot.
• It's unbelieveable that AOL/Netscape marketing people claimed that Netscape were now mostly about the website (which is of course complete nonsense and counter-productive for the Netscape browser and the web as a whole), just to hype the relaunch of the netscape.com website, an experimental (!) project for yet another portal.

And don't even get me started about the "copyright holders" like the music industry and the film industry. Listen to the first songs of Jennifer Lopez, and listen to her voice. Could she sing? Definitely no. Was it high in the charts? Yes. Anything is wrong here... (They fake the charts or the consumers are brain-washed by marketing.)

Not to mention the copyright protection and the related lobbying for bad laws.
