Mediocre products with huge market penetration are more likely to die a horrible death because: 1) they have maxed out their growth potential, and there are fewer and fewer converts for them to target. 2) since their quality is bad, better competitors are likely to gain viral growth by only contrasting themselves to the mediocre status-quo; its name recognition will be used against it and its brand sabotaged (i.e. "Like X but doesn't suck", "a better X", "an X with ..", etc.)
