True. But the team have shown common authorship between sections of the Book of Mormon and the Spalding text that they do have. There are also common phrases and themes as shown by Uncle Dale, the pattern of distribution of Spalding material throughout the Book of Mormon independently correlates with the authorship analysis pattern; both of these analyses independently correlate with the Book of Mormon distribution of material identified by Donofrio to include plagiarism from early American patriotic authors which mimics Spalding's plagiarism of the same authors in his extant manuscript.
The modern iteration of the "Spalding theory" posits the existance of Spalding material in the Book of Mormon. It doesn't claim that Spalding wrote the whole thing, or even most of it. Numerous other contributions have been noted by Criddle's contributors including View of the Hebrews and Campbellite theology. Joseph remains a significant contributor to the Book of Mormon.
The theory has a lot of explanatory power beyond the Book of Mormon authorship - both Oliver and Sydney colluded with Joseph on matters such as angelic visits over subsequent years. The Gold Bible Company hypothesis extends that collusion to the the creation of the Book of Mormon in the first place. As an example of what I mean by explanatory power, Joseph "prophezied" the arrival of Oliver before he turned up to work as scribe - did he actually have the power of prophecy? or had they colluded earlier.
