Yep, as evidenced by the "Source:Other" tag on ADSBExchange. Signals actually sent over the air would show ADS-B, TIS-B, etc, as the data source.

It’s only “other” at the very last point. Go earlier in the track and it shows as “ADS-B”, but every historical real flight in this plane is MLAT (it doesn’t broadcast its precise position but it can be inferred from receivers)

That's not true. And if you click almost anywhere else on the spoofed track it will show as Source: ADS-B.
