MacRumors, quoting Business Insider:

Multiple publishers have been unimpressed with the revenue generated from Apple News+. One told Business Insider that revenue was one twentieth of what Apple promised, while another said that it was on par with what was earned from Texture, which isn’t much.

I can understand why this is – when Apple launches a new service, it anecdotally feels that paid adoption is slow until there is a tipping point in perceived value.  I enjoy Apple News+ so I hope this doesn’t have any negative consequences to the service.
