I think I interpreted the article differently from you. I saw this as a cold hard look at what works and the dangers of changing your brand (or rather, the fact that "better X" doesn't always mean more success when you're Forte is Y), not some general argument against the idea of artistic integrity. Doing what Vogel can now do after 20 years and an established audience would lead to ruin for 99.9% of devs today aiming for financial success because the market is very different. And I'm sure he knows that.
