No, it was expected that the chinavirus would lose potency over time. Its origin is irrelevant. It's just natural selection that happens with every virus.
A virus strain that is less deadly and more often asymptomatic has much higher changes to spread than a deadly virus strain. Killing the host is not a good thing for the virus.
Yes but it's a matter of speed. The original virus wasn't very deadly to begin with. That means it wasn't seeing much selection pressure from killing its hosts too quickly. On the other hand, it makes sense that an artificially spliced virus is not fully adapted and would rapidly evolve before starting to stabilize.
