Neologisms like "simplisti’fy" are maybe ok in certain nerd circles, but they make the write-up less readable for the most important target audience: actual users of these badly designed "playground IT" systems.
I don't like it myself. But I want to differentiate "simplify" as in remove non essential complexity, from solving the problem naively, simplistically. Which is what a simple minded go-getter manager does. Lots of accidental complexity from nerd toys gets added in the process. So pretty much the opposite of simplifying.
You're looking for the German verb "Verschlimmbessern" :-)
