alt Hacker NewsI would actually expect the math to decode ads-b traffic is substantially less complex than, for example, a TLS connection.

It is trivial to decode, but don’t forget that tls is extensively optimised on most networking stacks.
TLS is supported in hardware, so it takes no more processing power than moving the data around without encryption.
In the US, ADS-B in uses 1.3 MHz of bandwidth, which would require 2.6 Msps. The ESP32-C3 running at 160 Mhz would have ~70 instructions per sample to process the data. That's probably doable, but the ESP32-C3 is one of the less capable variations of the line, and there are dual-core versions running at more than double the frequency, and those should be able to handle ADS-B in without issue.
