The sad part is that, despite the huge amount of (true) information available to them on the Internet, the majority of people seem to have become no more knowledgeable about the technology they use in everyday life. You can instantly look up the part numbers on that diagram and find out what they are; and if what you find you do not understand (e.g." what is an op-amp?"), you can continue searching. But the majority just take it at face-value, and re-share with zero thought. It's ironic to think that a lot of these people think we are the "sheeple", when they in fact behave much the same way...

And I lay it out for them. The short answer: is because it works.

If they send 5k emails out, asking for $2k, all they need is for a small percentage to fall for it.

They know how much effort to put in to get a specific return.

Why can't that be the same idea here? Pick out the ones who don't ask questions, or take 2 seconds to Google something, etc. Whip them into a frenzy. Then steer them to a specific site. Or to donate. Or even just start following whomever wrote this out, to be convinced to donate somewhere later.

This doesn't apply to the diagram. In this case, it wasn't just laziness. The author actually added not just the "5G Freq" label, but added "Bass", "Treble", etc in the exact same style. And I know they added this because I dug up an original diagram where the labels look different. The author erased the original labels and re-did them (and added "5G" to the pre-existing "Freq"). This was clearly a joke. Someone doing this for real would have simply left off the other labels and only kept "5G Freq" (or would have added other suspicious labels).
