We did some checking and well this one is untrue ! Sorry independent reported this in error it looks like they should have been referencing Bono's back injury which in fact delayed some of the dates of the 360 show.
In case you missed the original story
U2’s collective wealth is down for a technical reason. Manager Paul McGuinness left and is now counted separately with his own €180m fortune. If he had stayed, the combined U2 fortune would be closer to €900m, boosted by a mega $100m marketing deal with Apple and the release of a new album. The start of a world tour has been delayed by Bono’s bike crash but that should see even more money flow in.
