If someone is smart, then he doesn't do stupid things in life, regardless of whether it's about cryptocurrencies or something else. Being a beginner in something doesn't mean you can't be careful and research what you get into. Anyone who falls victim to these scammers cannot be considered an intelligent or smart person.
He was a Freewallet customer for a long time, despite he wasnt actively using this app. But anyway, first months the wallet was working. You also may try this trick - small transactions will be succesful. But if you try to withdraw more coins, the system wont allow you to do this.
So that you shouldnt blame victims of Freewallet scam. The fact they lost their assets doesnt mean they are stupid!
