I mean, it sounds stupid. The point of it is so you inspect your product, and then transfer the funds to the seller. When your coins are in escrow, that means that it's a guaranteed safe transaction, but then when someone FE, it absolutely ruins that safety. I understand that perhaps some reputable vendors want new users to FE so they won't have to deal with a hassle, but really, other than that.
Thanks.
Go tell that to anyone who had coins on a market that got hacked/raided/shutdown.
