I completely agree, I think this is mainly down to the mainstream people not realising the difference between an exchange and a wallet where you hold the private keys.
Cases like this though, do slow the mass adoption of cryptos, which isn't great. Perhaps these exchanges should hire some descent Devs that actually know something about security. Rather than solely concentrating on the front-end UX.
