It was that kind of attitude that has pissed me off at every company
I have ever worked for.  I'm fine with marketing to customers but I
hate it when people believe their own marketing.  Internally, I think
you should be very skeptical, judgemental, critical, whatever you want
to call it, if your code sucks or your hardware sucks, don't pretend
it doesn't, own it and fix it.  That's how you win.
