That's word for word the exact same article that appeared in the Chicago Tribune a week and a half ago, which in large part was a rehash of even earlier articles.
It makes its "case" by omitting any facts that get in the way. For example: "While Bono promotes charitable causes, he doesn't disclose whether he personally gives to them and, if so, how much." Yes, he doesn't disclose this for reasons he has stated many, many times, that charity, publicly disclosed, ceases to be charity and becomes bragging. He takes that part of scripture seriously and has made no secret of it. But of course they leave that out so as to imply that he gives nothing.
Another example: "I believe the ultimate charity donation is to pay your taxes in the country where you live," says some concert promoter. Firstly, that's a pretty odd belief. Paying your taxes is not a "charity donation", it's a legal obligation. Secondly, this implies that U2 don't pay taxes in their own country, which is of course completely untrue.
Thirdly, this is getting really boring.
