That user could have used it how other people use it.
There are a lot of things here that have nothing to do with “crypto needs to be simpler” copypasta. This particular thing was not simple and never will be unless everyone stops using it. Focus on that one thing: How to design a better smart contract? How to design a better UI for the end user? Thats a great discussion for a programming forum actually.

The user used a currency-exchanging thing, sent it a currency it shouldn't accept as input, and it swallowed his currency in stead of rejecting it.
What's "not simple and never will be" about that? Seems utterly simple to me: The currency-exchanging thing didn't work as it fucking obviously should. And the cryptards have the unmitigated gall to call this shit "smart"... Sigh. Geroffmylawn.
