SRKs are a special case but their recent low figures and troubles with calves seem mostly unrelated to those past captures and more related to issues like the lack of food, the use of sonar (nearby naval bases), boat noise, runoff from Seattle, and other issues (https://en.m.wikipedia.org/wiki/Southern_resident_killer_wha...). I get that the past captures reduced their numbers, which increases the risk of this community of whales disappearing, but it seems the lack of subsequent growth/recovery is due to other factors.
Orcas as a whole (the species not specific pods) aren’t marked as endangered and number in the tens of thousands. The SRKs are endangered and that’s terrible but I would say the overall orca species and even other marine life benefit from greater awareness and consideration from people having been able to appreciate them directly in places like SeaWorld.
Orcas are matriarchal, have extremely close family units, and rely on the leadership of older orcas. Killing or capturing orcas that would now be older orcas, particularly females, has had huge effects on the southern resident population.
