> I think the creators do legitimately want to build a truly open source calculator.

Somewhat like Google legitimately wants to "do no evil"?

Sometimes it is said that deeds, not words is what matters. But in this case even the words are missing, so I don't really get what you're trying to say.

My point is that ultimately it was more important for them to make a calculator that students could actually use - which is a perfectly reasonable goal. And it's a shame that that's fundamentally incompatible with FOSS.

Seems highly insane that students have to buy a calculator, that can basically never be used outside of school for many people because it's so limited....

Why can't the school just have a pile of them? Then they can be totally FOSS. The teacher hands you one, they know the FW is good, you give it back, and if you want to practice at home, you can buy yourself the unlocked version which would be fully open and have more communications so it could be repurposed.

Then the same device can be sold as a smarthome IoT remote like a better Logitech Harmony, or various other random uses, and have more economies of scale.

In fact, it could just be a cheap Android device sans GPS, with no front camera(A cheap rear camera is always good for QR setup) and with real buttons and a smaller screen.

Lower resolution + transflective display + 30hz + fewer background apps is going to significantly increase battery life.

Then people can try out the CAS features on their phone, and use their calculator for whatever they might want, since it's become the obvious choice for IoT stuff.

In Norway now a days, exams will provide an approved calculator for the student to use. This both reduces cheating, and let's the student buy any type of calculator they want for studying.

At public schools in the US, teachers have strong incentives to have their students perform well, as schools are graded on overall student performance, impacting awards, etc. Exam proctors would have to be independent from the school system if they were responsible for handing out calculators.

The problem is getting the calculator registered for exams

This is a viable issue that forces a choice on the manufacturers, which you aren't addressing. Of course it would be ideal if they had a second version (perhaps in a different color) that was fully hackable, and had some hardware difference, but that would be costly for them and hard to police.

Cheating is sadly a massive problem. I was shocked to learn from friends who did architecture in college that smart students would hide their final project models (physical models of buildings) inside ceilings and the like in the days leading up to presentations and judging, to prevent rivals from smashing them.
