Apple didn't want to buy modems from Qualcomm so they supported and bought Intel modems, but Intel failed to develop 5G modem to match 2020 iPhone so Apple make a agreement with Qualcomm (settle lawsuit) to buy Qualcomm's 5G modem chip and concurrently buy Intel's modem department to develop own modems.
It didn't pan out? Well Apple buying Intel's modem chip business seems like the opposite of it not panning out, at least for Apple.
