I trust sonarr and radarr to disable telemetry via the options, so I don’t think you have any benefits from putting them behind VPN. All download clients ofc make sense

I could imagine google also gets some sort of snapshots to mitigate the risk that after their announcement everyone deletes/modifies their content… But who knows.

Search all files for “http” and check how the URL is utilized, maybe you can comment out those Funktion calls

Same, would never do it again
