Ozone in the air is a bad thing. It's a polutant and bad for your health
The ozone layer in the upper atmosphere, however, is a good thing. It protects us from the sun's ultraviolet rays. And a good chunk of it is gone - forever.

Here's another thing to keep in mind about Roger -

The Who were the original masters of music acts planting inflammatory statements in the press in order to create a stir. Originally these comments were crafted by themselves and their management simply in order to get noticed. It was part of their 'shock and awe' assault and worked quite to their advantage in the squeaky clean mid-60's. Pete Townshend later became a master of this technique, and later finessed it into an art form featuring contradictory statements about the origins of songs, his political and social views, etc. Yet another way The Who highly influenced the punk movement.

Daltrey was a street tough from Shepherd's Bush who never really gave a damn about what anyone thought of him, and settled his disagreements with his fists well into his forties. I doubt that his statement isn't sour grapes or a well-planned scheme, nor a concoction to sell concert tickets. Just another pissed off guy speaking his mind, but knowing he'll create a ruckus by doing so.
