Your list of "already uncovered" fraud seems more like a list of RW hot-buttons: Clintons - check. Transgender - check. Various lame-stream media - check. Covid bats - check. Muslims - check. Incest movies - check. I'm just surprised they haven't turned up the payments for the NASA movie studio where they faked the moon landings.

But not a single administrator skimming off their department's budgets, which I would imagine is 90% of government fraud.

Also no-one is shooting the messenger. Mainly they are complaining that completely unauthorised people are rooting through all government data with no oversight. No matter what your politics, the president should have got these people vetted and followed the carefully designed processes to keep this data safe. If you're not seriously concerned that one day your tax info is going to turn up in an unsecured AWS bucket, then I can offer you a unique video of out-takes of Neil Armstrong falling off the LEM ladder for just $5,000.
