I know the guy personally, as he manages a campaign to bring BBC Three back and tbh, at times he will go overboard with what he types. Not that he's a bad guy, far beyond it, but I'm gonna be honest, I was waiting for a post about him here on this forum cause I wasn't going to do it.
I honestly don't see any problem with the Reith font, however he thinks it's better if the BBC were to go back to Gill Sans and he also thinks the Curves were a waste of money as well as saying he hates the BBC Scotland channel and the new BBC News graphics. The only truthful thing I share with him is that I don't see the purpose of a whole dedicated 'Scotland' channel but that's a tangent you can obviously read about over on the other forum.
I think it's more that he wants things to be old fashioned, it's not just because he wants BBC Three back. I'm not completely against what he says, but I do think he needs to understand that things can't just change back because one person demanded it.
