What an earth does that even mean? It's no wonder people keep messing this up. You need to spend half your life keeping up with the tech just to not get scammed.
I'm guessing the confusion is the "hex ETH" part. I know what a digital signature is and I can guess that ETH = ethereum, but have no idea what "hex" means so I can't "keep up" with your comment either.
I believe the malicious tx is basically serialized into a hex string, so not easily inspected by the user. As such, the wallet gives a warning, which the user ignores
This is the equivalent of being mad at banks because you don't understand what a bank routing number is.

The type of user that doesn't understand this should not even be using cryptocurrency in the first place.
