The most comprehensive software is powered by spaghetti code. I've just realised that if it's old/matured, it was almost nearly impossible for the code to be coherent or neat. No design patterns. A lengthy trail of ACLs and conditionals reading from a util/helper static method that would make javaScript callback hell's head spin and green with envy

These massive, ready-made software overbloated with features plastered in seem built in a hurry to churn out functionality to make stakeholder and client happy in the shortest amount of time. The authors are hailed as 10x devs. But to you, the maintainer, they are Tetanus that make you crave to rip your eyes out of their sockets
