It does seem to indicate that at least one of the problems they are facing is UAS...
I would think a brand new 737 MAX would have EHS capability. If so and if ATC did as well, maybe the 332 knot reading was indeed indicated airspeed and transmitted with the Mode S data.
However, based on previous news coverage of international accidents, often things get garbled in translation of ATC dialog in English to the local vernacular language and back to English again.
Has the claimed JT610 ATC transcript been published somewhere other than the gist given in the tempo.co article?

Is it likely as the ABC News article suggests that significant data may be recovered from the Boeing servers back home from the ONS? Even twenty years ago I was surprised how much operational and maintenance information was spit out in the clear over VHF ACARS by so-called modern airliners. Engine readings, fluid levels, EFIS alerts, crew lists with employee numbers (and in some cases SSN's
) plus the usual mundane text messages to call the chief pilot's office on arrival.
Even if Lion Air didn't buy the upgraded subscription to Boeing's inflight data services, would some of the information be transmitted anyway?
