It's not shocking that Apple would drop Qualcomm like a hot potato. There was word that Apple was designing Qualcomm-free iPhones back in October 2017, and relations haven't exactly warmed up since then with more lawsuits on both sides in addition to antitrust measures. It wouldn't be surprising for Apple to go Intel-only for wireless chipsets in the near future, for that matter. Intel is the only other company to have provided those chipsets to Apple in recent memory, and a wholesale switch to someone else's technology wouldn't happen overnight.

Whether or not Apple sticks to Intel is another story. Calcalists sources recently claimed that Apple had turned down Intel's Bluetooth and WiFi parts for 2020 mobile devices. That doesn't preclude use of Intel-made cellular modems, but it also shows that Intel's involvement isn't guaranteed to last long.
