Loro parque is known to host and reproduce a lot of endangered species of parrots and help it to recover from extinction with private money. As private zoo it has a very good reputation of taking lots of troubles to keep the animals as happy as they can.
They had an escape bat incident some years ago, solved, and there was the history of the killer whale Morgan with several animalist organisations figthing to avoid the park rescuing a deaf and starving dutch killer whale. It seems that some people would prefer the young lost whale dead than in captivity, for ideological reasons. Eventually Loro parque won all trials and collect all legal permits to keep an animal that would not survive a year in the ocean but is still alive and well and even has a calf in 2018. They even had to feed the calf with a bottle.

I'm not aware of anything really dark or wrong with them. Looks like a good modern zoo; In fact it is classified routinely as one of the bests zoos in Europe if I remember correctly.
What do you feel was wrong with them?
"As of 2016, 8.5% of the prisoners are in private for-profit prisons. Since 2000, the number of people in private prisons has increased 47%, compared to an overall rise in the prison population of 9%."

So, if the annual increase rate has not change since 2016, as of 2019 about 9.3% of the prisoners are in for-profit jails. [edit: computed the rate, it is not "more than 10%"]
The staff are passionate about looking after these primates and do not see the centre as a moral issue. The fact that the animals need to be rescued in the first place is the real moral issue.
Interestingly, the centre's worse reviewers are those who expect a zoo run for the visitors benefit, and who complain about the ‘untidy’ enclosures (i.e. good climbable trees that make it hard to see any action) or the fact that a given primate might have chosen to sit quietly in a sunny area where it has good privacy, rather than perform on demand.
