I think there's a line though.
Acronyms as jargon in a specialist field are reasonable enough: They're better than the alternative, which is to give meaningless cutesy names to everything. Pun or recursive acronyms for new things are the thing-inventor's prerogative. Nobody expects to immerse themselves in an unfamiliar specialism without a learning curve, and explanatory materials for non-experts should avoid acronym soup for clarity.
Acronyms that started off as jargon or useful abbreviations that have become part of mainstream language are fair game. Radar. CD-ROM. NSFW. HMRC. LGBT. That sort of thing. The problem comes where one person's mainstream language is another person's jargon, or when an acronym is overloaded in different contexts.
Acronyms as jargon whose primary function is to be a shibboleth for management types, with a side-order of obfuscation of the obvious to give the appearance of highly skilled work is another thing entirely. I'm sure they'd say the same thing about tech, thobut.
