It turns out Al Gore as a great typographical eye (apparently) and a sense for graphic
design. The design studio mgmt were chosen by Gore to design his new book
Our Choice, the sequel to An Inconvenient Truth. mgmt had settled on the
typeface Brioni for the body text, however after reviewing the proofs, Al Gore
didn't like the numeral one and wanted it changed.

mgmt turned to the creators of Brioni, typotheque and they agreed to make
the modifications.

'Al was right. The new numeral is a lot less confusing when combined with letters. We already changed it for all other weights of Brioni. We’ll call this ‘Gore’s choice’.

An excellent read and more on how these modifications are now known as
Gore's Choice http://www.typotheque.com/news/gore_s_choice

This baffling decision has been blazing trails on Twitter and elsewhere on the web over the last week.

Seriously, whoever made this final decision at IKEA should be sacked. I know this sounds reactionary and they obviously thought about it but it's just not logical. I am guessing it wasn't decided by a graphic designer or someone with know-how but rather by some executive who believes he or she is creative.
