This article is a bit... lacking. First off, the Flash updater on Windows works quite well on modern Windows systems. Second off, Ninite isn't just some good Samaritan, they're a for-profit company. Third, and related to the second, Ninite's updater costs $10 a year while Adobe Flash's built-in updater is free. They also have a Ninite Pro version that supports remote updates and installs and costs $240 to $2,220 per year.
In a similar vein, this is why Piriform cut them off from providing CCleaner via Ninite. Because automatic updating is a feature of CCleaner's business model, too. The paid version of CCleaner has automatic updates. Ninite was essentially taking that revenue model away from Piriform and using it for themselves. With free software supported by offers, Ninite is hiding those offers in exchange for cash. It's basically a paid ad-blocking service.
