The medical field is big too. The point is that it's your responsibility to learn things, not expect every piece of jargon to be explained to you.

I think you missed op's point. They weren't seeking an explanation, they were pointing out the initial sales pitch was too jargon dense as to be meaningless. The initial sales pitch might as well be in ancient Greek for your average engineer.

That doesn't make sense. Of course it's meaningless if you don't know the jargon.

The op says the product devs should "put in effort" otherwise the op will "skip over it and move on". This is backwards because it's up to you to learn things you don't know.
