You're unbelievably grossly misinformed.
Query me this, if you were a poor Sumatran gentleman and one of the world's most endangered mammals was risking the life of your workers, what do you do? Call RSPCA while thumbing through new shows on Netflix? Nope, because you're poor and you have literally no options beyond killing the thing because that's the way the world is when you're poor. Furthering this, if the reason why the tiger is there in the first place is because of deforestation because of palm oil crops, growing populations etc. etc. etc. how do you fix that without pissing people off who are trying to survive and feed their kids? And if people are actively killing these animals for alleged medicinal purposes, how do you stop that from happening too? And to top it all off, how do you actually breed enough tigers to offset all of this to stop them from going extinct while you're trying to fix all the above?
Let me be direct. You need great people and you need money. And a lot of it. And thank god for the amazing folks at Tiger Island, 21st Century Tiger and DWF who not only forward on 100% of donations to protecting tigers in the wild (which is spent sending teams over there and working in the community directly) but also work with many reputable international zoos as part of a large scale breeding program to go from "will definitely go extinct in the wild" to "oh wow, there's tigers in the wild again, and they're not suffering either, win!"
But you're right, giving the tigers at Tiger Island an improved space to exist whilst continuing to educate the general public which then in turns drives awareness and more donations is a terrible "debacle" as you put it.
We don't live in a black and white world mate where you can just throw animals into the wild and tell the locals not to kill them because it's bad. I'd also love to live in a world where every one of those tigers is back in the wild because none of them are being threatened. Sadly, neither of us live in those world, and if you'd like to live in that world someday, you should jump on the train and support those who are doing something about instead of being part of the almost satirically ironic position you put yourself into by being all for animals and hating on organisations who are making a genuine difference.
Still don't believe me? Here's literally dozens of academic papers for you to read that support every word i've said above.
