Apparently, the dolphinarium would only release Morgan if success was guaranteed without ever giving the animals a chance, completely ignoring the detailed release plan that considered all possible outcomes and provided solutions for those scenarios.
They knew nothing about Morgan or her pod when they promised to release her in order to obtain the permit; they actively hindered those searching for her family and when the time came to release her, they decided a collection of mostly hybrid orcas bred by SeaWorld would provide a closer family for Morgan than her located P-pod relatives.
How is it a commercial theme park is allowed to act as a non-profit rescue organization and can legally ship wild animals to another theme park? Because under the Dutch (and EU) Zoo Directive law, the parks are not considered theme parks but zoos and as such are not considered as primarily commercial, but educational. The permit to ship Morgan to Loro Parque was issued because the law states both parks are educational facilities and Morgan would therefor not primarily be used for commercial purposes but rather for education and research.
