I think the natural-virus-leaked-by-lab theory hinges on the argument that, (assuming it was true, then) had the lab leak not have happened, SARS-CoV-2 wouldn't have made to jump to human by itself. And this is where the Ebola analogy breaks down. Because SARS-CoV-2 has a higher basic reproduction number than Ebola, meaning it's more transmissible. And it's also much less deadly than Ebola, meaning it has much more opportunities to spread.
Remember, it is a virus that caused a global pandemic, despite all the efforts made to stop it. Based on that, I think it is highly likely that whether the lab leaked it or not, it would have made its way to humans by itself. In other words, there would effectively be no way to tell one scenario from the other.
