I'm kinda in the middle on this. I have no problem being honest about the dead. Steve Jobs' business practises and products should be open to criticism, just as much as they are open to praise. Even now that he is dead.
Personally I've always seen this "don't speak ill of the dead" thing as something that involves personal relationships, and being able to let go of a grudge against a person who is now dead. There is no point in any kind of one-upmanship with a corpse, but neither should you feel the need to lie.
For example, most people know my views on Craving Rod. If I found out he had died, I would be honest and say that I neither liked, nor respected him. However, I would not explain that I thought he was a truly worthless human, and that I believe the world is slightly richer for his passing.
There is no point in bitching about the dead, but pretending they were great people in hypocritical.
