The email address is such a big teller in this case, I wonder if there are actually people who can fall for a scam like this.
Sure there would, he knew just from experience(as he mentioned above) and he has the knowledge about it, what about someone with just basic knowledge of just holding Bitcoin On their HW wallets.
Good that he is creating the awareness because the template design looks pretty much convincing at first glance, I don't know how trezor email templates looks like but they must have tried to immitate it... the sent out could even be in bulks, hopefully this save someone.
