well partially true, they take some good money for their licenses,for example:
https://fastoffshore.com/what-we-do/packaged-services/online-gambling-license-in-curacao/ - "The Curaçao Online E-Gaming Businessbenefits, Package is available for an initial set up cost of only US $19,850"

but they do provide benefits like lower taxes, regulating bodies

and as a player ,at least you know who to contact if any dispute arises
