An usage right is the right to use something someone else owns.
In this case, the 8048/JAZ license holder gives non-exclusive rights to casinos to operate under its 8048/JAZ license. But this issued right has no legal basis because of the above mentioned reasons.
So, once again you are not being very specific. Typically usage rights are related to copywriting issues, such as music or literature.
In the case of music, a writer produces content and a third party might want to use the music for an advert whatever and therefore they seek agreement on usage rights for that content.
According to your brainology, Direx N.V. having an usage rights contract with the 8048/JAZ license holder to operate under its license is not specific?

You probably live behind the moon, but you can have an usage right to use any kind of things and even properties.

The Curaçao government would have a licence type which allows for 'white labelling'.
Would have or have? I trust you are able to understand the huge difference.

Can you show us the license type issued by the Government of Curacao allowing 'white labelling'?
Can you show us the white label issued by 8048/JAZ license holder Antillephone N.V. to the operator of oshi.io?
As far as I have seen, only companies can claim to operate under the 8048/JAZ license. Please tell us the name of the company that operates oshi.io?
I already asked you earlier, but you ignored to answer this important question!
So, once again you are not being very specific.
The licensing authority authorises an operator to use an appropriate licence and the operator then works with marketing partners within a white label framework.
Who is the licensing authority in Curacao?
So, once again you are not being very specific.
Did the licensing authority in Curacao give a license to oshi.io?
So, once again you are not being very specific.
If yes, please show us the license issued to oshi.io?
This framework is used with numerous gaming authorities, so I don't understand where the legal irregularities are?
What framework?
So, once again you are not being very specific.
Who are the numerous gaming authorities?
So, once again you are not being very specific.
And besides which, you've never put together a coherent legal argument on any thread I've ever read from you.
You did?
