I have spent my career in IT. All of the stuff he found proves the system was not secure, but none proved nothing around the system having been hacked.

If someone with hacked the system and changed the election totals, they also some how got the physical ballots changed.

From a tech stand point, this was a huge nothing burger if you wanted proof that Trump won.

The voters who voted more than once is something, but there is no way to know if those votes were for Trump or Biden, so the only thing that could be done is decertify and revote with new protections in place.
