Because ...

An ugly bit of propaganda is out there trying to distort the facts:

At Russell’s urging evangelization was renewed, and The Herald of the Morning was restarted, first as a quarterly and then as a semi-monthly. In later years Barbour would suggest that Russell tried to steal The Herald from him. In fact, in the earliest issues of the resuscitated Herald Barbour acknowledged Russell’s part ownership by including a box, usually on page four, that said, “Published at Rochester, N. Y., by C. T. Russell and H. H. Barbour.”

Ownership and publication details were reported to Rowell’s American Newspaper Directory, doubtless by Barbour himself since Rowell sought information directly from the publications he listed. The Herald of the Morning's entry in Rowell’s 1879 edition reads: “Established 1873; N. H. Barbour editor; C. T. Russell and N. H. Barbour, publishers.” In this light one must conclude that Russell had at least a half ownership of The Herald.
