I'm sorry, I work in tech, and I think this audit is a PR stunt and a debacle, but I do not understand your claim that obtaining admin passwords to a router like the Linksys unit in your photo would expose voting history and other personal information. Normally it would provide access to router configuration information. Some recent logs of exceptional system events (e.g. router rebooted) might also be available, but commonly it would only cover the recent past measured in days. Per-packet metadata would require a lot of storage, more than a router would normally provide, and payloads significantly more, especially to cover back to November 2020. Even if these were very unusual routers with that much storage and that much history, what makes you think that voting history would have been in the payloads of the packets handled by these routers? I would expect the payloads to carry information from ballots, and actual votes, all encrypted to thwart an eavesdropper who had compromised the router.
I agree that the Arizona audit is nonsense and dangerous, but adding nonsense to that is not helpful.
