The original article was talking about simple tax returns. In fact, the 1040EZ is relatively new. Much newer than the existence of H&R Block. So evidently their efforts to keep taxes complicated aren't entirely successful.

Even a 1040 "long form" (2 pages) with itemized deductions for mortgage interest isn't that complicated.

I file about a 10 page return, 1040 with schedule A, schedule C, self-employment and various others and I always do it myself on paper.

If you are at the point where you think you need TurboTax, you're probably better off just hiring a local CPA firm to do your taxes.
