Partner is sucked into a “crypto cult” in my opinion. How to help?

Tldr. Partner thinks Bryan Legend can do no wrong. Nothing he has said re his thoughts and opinions about the devaluing of the absolute useless,no utility rebase coin has panned out. Nothing will convince him he’s going to either do a rug pull, continue to withdraw for “marketing” or that the price will drop to zero. Tried to point out the obvious etc multiple times but he’s insistent its not a cult. Absolutely follows cult behavior in my opinion

Any tips? Has anyone else gotten people to successfully realize that certain projects are scams ?

PS this guy (BL) has done this stuff with multiple other projects. Somehow 1000s of people keep getting duped.
