To clarify my point, it's really about priority. The main motive behind any web business should be bringing your particular service or product to the public - and having something you believe in as better or different than the many alternatives that are available in every niche. Having that core offering is the top priority.
From there, of course you publish with the clearest possible signals that you can muster for Google and other search engines. But the problem many run into (and this network of domains in particular) is when those search engine signals take top priority and the rest of the actual offering is just TweedleDum joining all the TweedleDees that are already out there. There's no way I can see that a solid business concept "needs" 3000 exact match domains for proper execution.
More and more, Google is not pleased with the "SEO-first" approach, because it generates content farms and even spam networks - a flood of content that no one really needs or cares about. If your "SEO" approach mirrors those footprints, then you will be in trouble eventually, if not sooner.
