The wireless industry doesn't look very blown up to me; in fact, the iPhone appears to be a step back since it is only available on one carrier, while most other phones are non-exclusive.
But the article isn't (directly) about consumers; it's about the power relationship between wireless carriers and device manufacturers. The wireless industry is "blown up" in the sense that it lost a power struggle with the manufacturers.
Remember: five years of exclusivity is virtually the only thing Apple had to offer Cingular. (Plus a tiny slice of phone and music sales, but that's not huge.) Contrary to the old system, Apple retained full control over the development and marketing of the iPhone.
