Apple subsidize OLED manufacturing by buying up Samsung touchscreens, which directly feeds into the photovoltaic manufacturing chain (solar panel and OLED manufacturing is largely the same).
Apple subsidizes Telecom chipset manufacturing by buying up Qualcomm and Broadcom chips, which directly feeds into Military and Industrial IoT applications.
Apple subsidizes SoC research and manufacturing, which directly feeds into Military and Industrial IoT applications.
Apple subsidizes Battery research and manufacturing, which directly feeds into EV. BYD was originally a battery supplier for Apple before they entered the EV space.
Apple subsidizes CPU and chip manufacturing, which directly feeds into smaller and more efficient chipset generations.
Apple creating the first App Store in the World subsidized mobile app development, which directly fed into scaling out Digital Infrastructure like eBanking, BNPL, Microlending, etc
China's entire dual use supply chain can be attributed to the scale of Apple (and Samsung's) supply chain there, and both companies are having a similar impact in Vietnam and India now for the exact same reason (eg. all Samsung OLEDs are manufactured in a suburb of New Delhi now, 50% of all Samsung phones are assembled in Vietnam, 25% of all iPhones will be assembled in India by 2025, Airpods and other small consumable electronics by Apple will be assembled in Vietnam, etc)
