No amount of OPSEC lectures or packet inspection is going to sufficiently keep the carrier's private information private. There's thousands of sailors on these things. When details like its location and readiness level actually need to be secret, all regular internet access should just be cut off. Radio silence. I assume this person had internet access to use Strava because the carrier isn't yet in some higher level of readiness and its location isn't yet considered much of a secret.

With how bad the human experiment generally is, I rejoice in the fact that our own stupidity will be our undoing. Imagine if we did things correctly.
