The always outspoken Osbourne matriarch is not impressed by U2's move, in case you were wondering. In fact, she felt so strongly about it that she took to Twitter to go on a rant. It started with her saying what many have noted: "U2 you are business moguls not musicians anymore. No wonder you have to give your mediocre music away for free cause no one wants to buy it."

Her last point, that no one buys U2's music, could be argued with since U2 are one of the few bands who've relatively managed to retain their sales amid the music industry's changing climate. Case in point: their last album in 2009 No Line on the Horizon moved 5 million units. Osbourne's overall rant, however, suggests that she has more of a problem with the invasive delivery method of the album and Bono's political persona.

She also added that "This is an invasion of my private space. My entertainment space�" and tweeted more directly, "Whose political a** are we going to pull you out of today? Or are you front row at another tragic fashion show?�"
