It's a long article of a dude trying to convince others that he's not responsible for his own actions and it's someone else's fault when he does something wrong.
Exactly. Day traders generally say "Don't fall in love with your shares" and he very clearly did. I don't think it is Robin Hood's duty hold customers' hands and influence their strategies, and it probably isn't even legal for them to do so. That duty belongs to a financial advisor. You probably don't even need a financial advisor to know when its time to sell some of the shares to put money into other companies that'll hopefully be on the rise. The increases he claims to have had is as clear a sign as any.
Besides, I think all the information he complains wasn't available to him is right here: https://learn.robinhood.com. If he thought that was too boring or complicated to run through, then it is only his fault. If investing was as easy as he was treating it, Warren Buffet would be the average.
