Can you elaborate on why you think this isn’t relevant? It seems plainly obvious to me how it’s relevant.
If you're curious about the DVS topology: https://www.sos.state.co.us/pubs/elections/VotingSystems/sys...
A vulnerability in the FTP software, which I don't believe you've provided any proof was actually exploited in the wild during the elections, makes 0 difference to official results.
No one is saying they were hacked this way but it definitely can be used as fodder to bolster election fraud claims (real or imagined.)
Do you have any evidence to support your claim?
