Consider that Tether is obviously a scam but continues unabated to this day. Better tooling is not going to fix the problems you think it will, because the incentives are all stacked toward dishonesty and fraud.
First, the greater community that would "accept" such an audit that is simply proof of on-chain funds is not dumb enough to download some random "Bitcoin wallet" that shows fake numbers for one single company.
Second, the fraud you're alleging Tether is doing is off chain! It's in the fiat world! It's not happening on-chain. Stop blaming a system that literally mathematically precludes fraud (within the system itself, of course).
