Although he sounds honest in the video, I don't rule it out, really. Some people have an art for deception.
Some people looks for sympathy to get moral support or for donation, only the person knows the reason behind his action. About people looking for sympathy in order to get some financial support from their listener, it happens everywhere. We have seen people do that, not only online but in the street as well. Others are even knocking on every person's door to ask for help while presenting that they are in distress and in need but I am sure most of them are just modus operandi to trick people.
I don't say that this person do this stunt to get money from its viewer but if there is a donation address posted on it, then it is clearly the case but it seems the person story is real since he is not asking for any donations or whatever that will benefit him financially.
I believe he is sharing the story in good faith, that people will learn from his experience and learn to secure their financial account properly that hacking incident will have a very slim chance of happening.
