I read the article a bit differently from you, Foro - not as much as an expression of opinion about the situation, more like an analysis. And I think he is spot on in that analysis.
If this actually was about "four brothers, one unity, one last time together", then it should be easy for Tony/Ozzy to give Geezer and Bill equal shares in the tour profits. The way things have turned out, indicates that the motivation was - indeed - money and not much more than that.
You and I may not like it, we think that the idea of a tour with the original lineup is great, but that all members deserve an equal share - but if that was indeed not the intention of all four from the beginning, then it was always going to become a question of money. It's disappointing, but it seems like it is correct.
You might be interested in seeing Sabbath without Ozzy. But Ozzy, Tony, and of cause Sauron, know that many wouldn't. They know that it is easier to sell tickets for a lineup featuring Ozzy - just like it is easier for Maiden to sell tickets with Bruce as the frontman rather than Blaze, or for Priest with Halford instead of Owens.
I did long consider going to see Sabbath (it would be my first, and only, chance to see the original lineup!), but now I'd rather not. Not when I know that one of the original members didn't join the tour because the others wouldn't give him his fair share.
