Except on small memory / processing devices (like ESP32) it's not actually that simple. Processing ADS-B on an ESP32 would, likely, be easier.

Part of the reason I've come to understand how finicky TLS is on ESP32 is because there have been a ton of TLS issues with these devices in Home Assistant [0]. The linked issue just being one of them that's still not fully resolved.
