You Aren't Google or Apple (so don't design your home page like theirs)

Slamming them with row after row of buttons and boxes is disconcerting. For a new company I would say that simple is best, as long as it is elegant simplicity.
Asceticism is a whole different story. Your page should have just the right amount of appeal without being loaded down. I feel that Google, Apple, and others have mastered this fine balance, and that is perhaps the reason why it is better for new companies and startups to not try to imitate it, at least not right away. It is a hard thing to master because if it isn't done properly it will ruin the effect.
However, if a startup can pull it off right it will be much more successful then a similar complicated interface.
I don't know what the specific language you're referring to is, but I do imagine an issue with expressing "the main operation of the website or application" too prominently in something like a marketplace. Imagine if eBay or Amazon tried using a huge splash that took up the entire area above the fold to explain what they were about.
I guess you could argue that in a marketplace type of site, the "main operation of the website" is expressed through displaying all of the various items for sale; but that's not the type of design that would come from the thought process this article warns against. PS not saying that's what you're implying, just observing.
It probably isn't as sexy as an Apple computer, but that doesn't mean you should feel the need to hide it.
