Or simply different styles and/or skill levels were mixed. I'm currently sifting through a code base that I know for a fact started out goodish, but through multiple team reorgs and lax standards/tight deadlines it devolved into a hot mess. A major contributor being that most of the devs were inexperienced in the framework and just did what they thought was right.

Even supposedly senior devs often have a "I know best" mentality and when they get their hands on a code base do it their way, with the result that after something went through a couple of hands you have a mess of different coding styles and even different software design choices in the same code base, or in other words, and unmaintainable mess.
