With no more understanding than that, it seems to me that only people who do not have permission to 'use' your music would have a problem with your Content Identification.

CID is likely the digitally embedded data in your recordings that the Shazam application picks up by just 'listening' to music coming out of a radio, or other device, and enables it to 'Identify' the Song title and artist.

If the person putting it on Youtube, just for an example, does not have authority to put it on there, it might be blocked. You may want to query someone at Youtube to see what their explanation might be. Any 'user' in the commercial realm, using your music to make them money, should have your permission to do so, and your ability to know about it, to enable collection of your Royalties in exchange for 'use'.

What 'use' is your Publisher making of your music that they would NOT want your Content ID data in it?

Content ID is likely how terrestrial radio tracks plays, and reports them to your Performance Rights Organization, for calculation of your Songwriting and Publishing Royalties. Why would you NOT want that data documented in any 'use' of your music?

I think your Publisher should have more of an explanation than you seem to have gotten so far.
