A driver for the use of Acronyms and initializations is, for those that are speaking or typing, to actually sound out or spell out every word in an acronym or initialization slows down the transfer of concepts to the other person. This is all well and good when the other person has the context of what you are speaking about. "I pulled out the CB, then started talking." is ambiguous, unless you know the context is burning ones fingers with a soldering iron.
A second use of Acronyms and Initialisms is to "appear to be" superior to others when speaking about a subject. A mental "can you top this" sort of thing. Those that do it intentionally to others as an intentional way of crowding them out of a conversation deserve some sort of punishment.
One of the many problems with Acronyms and intializations is that of repeating a part of the acronym in the sentence because the speaker (or typer) forgets what the acronym stands for in the first place - a too obvious example - Three letter TLAs are a problem. However, I can understand how these can develop - someone misuses the acronym, then others have to clarify the acronym when they want to use it properly.
