I don't think it's meant to seem concerning, just interesting, and a different perspective on Apple decisions that affect device transfer and repairability. These days I really don't worry about Apple making ends meet.
This bit could become a problem:
Since 2012, the Indian government has mostly blocked imports of used iPhones over concerns about e-waste and domestic production. Apple repeatedly pushed to overturn the policy in the years that followed, according to reports, but the government held firm. With no old iPhones coming into the country and few new models being sold, there's a limited number of phones that can be refurbished.
It's easy to imagine scarcity further incentivizing iPhone thefts and expanding illegal import markets. Those are problems that would exist anyway of course, but it could make them worse.
