'Success' of course needs to be defined in a context and yes, in general he is talking about financial success, but the specific issue in his post is so-called 'spiritual business'. He talks about 'increasing light'.
My point is that for a 'spiritual person', true success is aimed for in the long-term measure - the one by which we are ultimately judged - whether deemed to be judged by ourselves or a third party. So to ask, in the context of 'spiritual business' about success, meaning financial success, is something of a contradiction in terms.
I never trust the word "spiritual", especially when it's wrapped in quotes.
I'm an atheist. I don't believe in an afterlife. What happens in this life is all we get. To me, any effort spent hoping for anything else is folly.
I look at "success" from a neutral lens. There isn't just one form of success. In my mind, success-through-great-product is a desirable success. So is success-through-never-needing-money. Both of these can be achieved through ethical failure. You can make lots of money through breaking laws. You can break rules to more easily design your product. The question asked was: can people succeed at all by being clean? And Seth's answer was yes, because the Net exposes more to people and it stops people from being as easily dirty. That's a good thing! Absolutely!
Just don't take that answer and turn it into a matter of morals being all that matter, because they don't. Amoral people are still succeeding in the world, and I doubt they'll be punished for the crimes they've committed. Some might. Certainly not all. His point was that you didn't have to be dirty, and that's a positive enough answer without moral certainty becoming involved.
