Uhm well so what's your point finally? You said that they'll publish a book about "hacking" but you didn't tell us why that should be a reason to boycott them...
in reply to Boycott O'Reilly
I like O'Reilly books and I like hacking. And I don't see anything bad about publishing books about "howto hack". If you're not skilled anyway you also won't be able to write exploits after reading such a book.
Also if you think keeping the web secure means to avoid any information-sources about howto write exploits you have a really stupid idea about how security should work.
It's even positive for security that such information is available and the more widely it's spread the better. Why? Because programmers maybe start to think more about howto avoid exploitable code when they know how it could be exploited...
