Since this standard business practice is not going to be accepted here on Hive, I have decided to move on.

Why not? I am not a legal expert, but if you purchased something, and if you have the license to use it even for money earning, then you have full right to publish that content on the Hive blockchain.

Especially after they say that (You CAN) "Publish the content on your own blog".

And people usually monetize their blogs, not just/only on the Hive blockchain.

As I understand this, white-labeling is not a bad thing at all, because it involves a mutual agreement. So it is indeed not a plagiarism.

By the way, you wrote "plagarism" instead of "plagiarism" on the cover picture/image.

I hope that this situation will be resolved, and you can continue your activity on the Hive blockchain.

Have a nice day. All the best. Greetings and much love from Hungary.
