Neat indeed; you seem to have discovered lots of interesting tidbits.
Of all you mention, two are extremely surprising to me, and I'm not even sure which is more - China course corrections and GPS jamming. The former sounds straight out of Cold War counterespionage playbook. In this day and age, why would they bother? The latter... again, are drones really that big of an issue to justify the jammers (and, presumably, legal clearance for jamming GPS)?
