Use of abbreviations is one of the greatest contributors to cognitive complexity I've seen in code. There's been plenty of times that I've renamed the variables in a method and all of a sudden what was completely inscrutable is really very simple. Acronyms are a particularly nasty subset of abbreviations because they're accepted in discussion of business needs and even in tutorials and documentation.
