Mine is when they've just read a fluff piece in a magazine or just wasted money at some echo-chamber "developer conference" and now magically, with ZERO programming knowledge, think they have a better command of what languages and tools I should be using to build their programs.
As always, frameworks are some of the worst offenders for this -- given that universally they are incompetent garbage yet SOMEHOW end up the media darlings. Doesn't matter how inefficient, or directly in conflict with good practices they are -- one positive article in Forbes and we're stuck having bosses, clients, and other people not qualified to write a single line of code shoving this trash down our gullets.
Which as I often say: "Taking technical advice from the pages of Forbes is like taking financial advice from Popular Mechanics -- before you know it you're bankrupt for having sunk all your money into pseudo-scientific SCAMS like Moller International, electric roads, or half-witted pipe-dreams like hyperloops."
In that same way without the qualifications to know if it's bullshit or not, those who don't know the first thing about programming know things like bootstrap, wordpress, node.js, vue, react, etc, etc as nothing more than buzzwords and not what they are for, when to use them, when not to use them (which in most cases is the case), but STILL insist that those working for them do so.
To the point a few months ago I actually had a client say "But you can't build a responsive website without bootstrap!" FACEPALM -- or even MORE classic about two years ago someone said to me "use bootstrap, nobody builds websites with HTML anymore!" -- I was not kind in my response: "What the f___ do you think people use, marzipan and kittens?"
It's almost as bad as a decade ago when someone would ask "how do I make a link turn red when hovered" on a forums and some know-nothing twaddle would say "Use jQuery".
Which the susceptibility to treating technologies as sick buzzwords or "the solution to everything" isn't exclusive to non-programmers. We see it all the time as "I know this framework so I'll use it for everything" just because they don't want to learn the underlying langauge -- and clearly don't know it well enough to even recognize if said framework is making anything simpler or harder. (and most of the time it's the latter!) The end result is most always like someone drove a screw with a hammer. Developer conferences being one of the worst for creating this situation since they are nothing more than echo-chambers filled with head-bobbers, with anything resembling dissension being stamped out, ridiculed, laughed at -- EVEN as those running the show are basically talking out their arses! Hardly a shock the result is a confirmation bias rooted in cognitive dissonance much akin to how cultists behave.
But when non-programmers encounter the same propaganda and ritualistic indoctrination the situation is a thousand times worse as they have NO clue what the blazes they're talking about, but insist on telling others how to do things and what to do them with.
