You are accusing an international corporation of maliciously software crippling millions of devices worth billions of dollars. With that in mind, this is easily testable and has been researched and debunked in the past. If apple was caught doing this there would a multi-billion dollar class-action suit. What’s more likely is each new phone is significantly faster and more efficient than previous iterations. Thus, new software designed for “current” devices will run dramatically slower on a device even two years old. Fun fact, the most intense gain being made in processor tech is by apple and their SoC tech. Each new A series chip blows away competition to the continued amazement of most.
