It's really not. The overall tone is "You don't know anything about finance/accounting as an inexperienced leader but that's okay! - Just outsource it! Oh and here are some tidbits so you can pass off as knowledgeable in conversation"

It's not tone - it's explicitly targeted at people who don't know much/anything about finance/accounting and almost by definition are relatively inexperienced at running a business.

There isn't a great alternative. Taking the time to become an expert certainly isn't a good idea. Hiring a CFO with seed money isn't a good idea.
