Even if TI cannot be displaced, the amount of money they're extracting could be drastically reduced.

The only time these calculators are actually needed is in exams - it should be pretty straightforward to let students use a TI clone app on their phones for regular study, and give them real ones only during exam time.

This reduces the need from 1 per student, to 1 per students concurrently taking an exam.

This is already the case, and has been for decades. It is entirely possible to get through high school and undergraduate math/science education without ever owning a handheld graphing calculator, just borrowing one for the 1–2 exams which require them.

A “scientific calculator” (or for that matter a slide rule) is pretty much always sufficient in class, and a computer with a full keyboard and proper programming language (this could be a chromebook with a web browser, or a Raspberry Pi or used iPad with an external keyboard) is a better homework tool.
