Exactly. The smart thing to do would have been to use a special variant of Reith for the logo, thereby allowing them to get out of paying the Gill font licensing costs but avoiding the legibility issues.

We've discussed this before, but there were no licencing costs for the logotype - they even trademarked it.

While it uses Gill Sans Medium, it's actually a drawn element - which is why the original plan was to retain the blocks.
