After the first two paragraphs i was deeply convinced that you were questioning the products those puzzles were part of, not just the way those puzzles got in there. The cynic in me likes to widen the scope one step further, then those figurative 80% are the fraction of software created that is basically "twitter for pets" (or some transitive dependency thereof, technologically or via business). It's easy to focus on one of the many exciting puzzles hidden inside a "twitter for pets", but if you take a step back (and yes, that's one of the perils of age), well, twitter for pets.
