Scott Manley has a pretty good video overview of the whole thing if you want a boot up: https://youtu.be/74_N163HyhA
Telemetry interception could be a problem for sensitive (i.e. government) launches. I wonder if they will need to mitigate this for the first stage.
Could also be a problem for general launches if the telemetry has information which is not disclosable due to ITAR.
