Is Rob Braxman a fraud?

Rob Braxman a privacy advocate. This is his channel https://odysee.com/@RobBraxmanTech:6 . He claims to be one of the top most creators on Odysee. I have heard people say that he doesn't really know what he is talking about and its best to not watch his videos. He also runs a company that sells degoogled phones and VPN devices and a social network site What do you think?
