Why this is a false positive

Building a ground-control-station application for hardware the user owns, by studying an existing app's communication protocol, is standard interoperability/reverse-engineering work protected under exemptions like DMCA 1201 and routinely done by hobbyist and open-source developers. The conversation explicitly frames this as first-party device research ("your hardware and your property"), not an attack on third-party systems, yet the safeguard triggered on generic "cybersecurity" keyword association rather than assessing intent, scope, or authorization context. This blocks a legitimate, narrowly-scoped, single-user engineering task with no plausible victim or unauthorized target.
