The last sentence is why I have not added PandoDaily to my feed subscription list. The fact that they list three companies competing in a market means they are unlikely to be "disincentivized to pursue innovation." In fact, Intuit has regularly been acknowledged by the likes of Forbes[1], Inc and Fast Company and Eric Ries's Lean Startup book as being one of the most innovative public companies. Not only does it show a lack of critical thinking on the subject at hand, but it's passing that lack of knowledge onto the reader.
ZenPayroll is tackling a huge and highly profitable market. They're probably attacking it faster than their public counterparts. But to say a company like Intuit, along with Paychex and ADP, are not innovating because they're "disincentivized" does a disservice to ZenPayroll and its competitors.
I'm just guessing, but I don't think ZenPayroll takes any of its competition lightly and is working as hard as it can to break into this market precisely because it has formidable competitors.
