The problem with Aave lies with Aave. They are the responsible party for relying on a faulty price oracle and not responding to the bridge hack fast enough. It took them weeks to decide to stop borrowing and then reduce interest rate. Now they are trying to wash their hands of the problem by blaming harmony for allowing the bridge to be hacked.
If you are expecting harmony to respond to this you then you are expecting harmony to fix somone else’s problem.
