Yes. I support a local non-profit ape rescue centre. The vast majority of their primates were rescued from the pet trade, medical research, beach photographer props, circuses. Some have disease (e.g. rickets) / deformities from poor diet in their pre-rescue lives, while others lack social or survival skills. Some have physical injuries, e.g. from their teeth being knocked out by their previous owners. These factors mean that a return to the wild is rarely possible (assuming the original environment still exists).
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.
