I realize Muze is a database, not a catalog, and does not come in "print" form.
I don't care what "Muze" thinks, I care what "Rovi" thinks, as Rovi purchased Muze.
When eBay took over HDC, they also removed many categories for which the add/correct catalog was needed, including Everything Else.
Since eBay/HDC pays Muze for a database offering, eBay/HDC does have the right to let Muze know their concerns, comments, and complaints. No company that subscribes to the database can manipulate the database, unless they have the platform to do so. When eBay merged HDC with eBay Media, they removed such platform, and made HDC fit the eBay mold.
One can blame the subscriber... but the content provider is the guilty party. eBay is only guilty of not subscribing to a supplemental database, or creating their own to fill in the gaps.
