I think this is down to the educational market. For many exams you can only used an approved make/model calculator.

If you can hack the OS you can use it to store answers, notes or similar aids in cheating for an exam. If the platform isn't locked down they'll lose their exam board approval which would have a big impact on that models sales.

I don't think TI is still selling the 83; they've moved on to promoting the supposedly new and improved N-Spire.

The 83 is still listed on their product website -

Notice on the page it also says - "Count on TI calculators at exam time. You can use this TI graphing calculator on the PSAT, SAT, and ACT college entrance exams, IB, and AP tests."

The TI-83/84 is still used in a lot of textbooks, and teachers are loathe (sometimes) to learn something new. It's entrenched.
