There is no financial or any other penalty for keeping the lie there, so it won't disappear.
For years Omega used to write "the first and only watch on the Moon" on their Speedmaster watches, even though people kept pointing out over and over and over again that it's just simply not true - other watches were also used on the moon, including a Bulova Accutron when the nasa-issued speedmaster popped its crystal while on the lunar surface. So it was an obvious and easily provable lie, but for years it adorned a multi-thousand dollar watch. Omega did eventually change it with the new revision of the watch, but there is no reason to believe that it was because people were complaining about it.
