People buy it because they know that Sony will never let them down.
I suppose these "people" never bought a CD from SONY/BMG that installed a Rootkit on their computer opening it up to hackers and sending information about your usage habits.
I suppose these "people" never bought a laptop from Apple/DELL/other companies that had exploding SONY batteries
I suppose these "people" never bought a Minidisc player, or a Betamax player, or another of SONY's failed formats
I suppose these "people" never had to import anything from Lik-Sang because it takes a year for games to make their way from the USA to other countries such as Australia.
I suppose these "people" never bought content from SONY that was encumbered by DRM and couldn't play in any media player.
I suppose these "people" have never been sued by SONY and their RIAA partners, or had their 10 year old daughters or dead parents sued.
I'm sorry, SONY has let me and many people down over and over again and finally they're seeing the backlash from treating their customers like shit for years. I and many others simply don't trust them any more and don't buy any more of their products, because I don't know what they will try next.
Of course, you're more than welcome to keep accepting their crap, it's just unfortunate that there are too many people who keep buying their stuff and they can justify their unlawful and unethical behaviour.
