Ah yes, the "people use calculators in the real world so long division is a waste of time" argument
That’s flatly false.
Please don’t spread FUD. Your ignorance of better solutions is not proof they don’t exist.

You're saying Google doesn't have privacy issues?
What would be the threat model here? Google would crawl the templates of the exercises and use it to fine tune their ads to the parents related with that content? NSA would know that Michael doesn't know that 4+4=8? Thinking about risk analysis, would you take this risk instead of invest taxpayer money? In my case in Germany, each State is coming up with their own solution, developing something which doesn't attend the minimum requirements (feature wise, privacy wise, supported platforms) and etc. For example one issue that we found in the last months: A lot of refugee kids have just a mobile telephone, but some solutions don't support it well. What do you think about usability? Totally wrong, Language Support? Just German (Yes many kids came to Germany and their parents don't speak German, how can they help their kids with something that they don't understand?), I could write hours about how wrong all evaluated solutions are.. And for sure their are not opening their source code, so how is it better?
Regarding Privacy, do you trust your data to your country more than you trust to Google? Maybe you do, but that's definitely not true for everyone or every country.
P.S: Look that my first statement and whole argumentation is based on the COVID-19 scenario and the issue that I'm raising is if any Country or State should be building their own similar solution with taxpayer money in a short amount of time.
I earned my living with Blender as a VFX Freelancer (in Europe), so saying Maya is a must here is a bit outdated IMO.
1) the software you teach them should last them for a while. That means it shouldn't be to limiting (even if that means more user friendly). It should additionally be something where you can assume it will be around for a while in that form.
2) It should make it easy for them to work in the field that they are in.
3) The work they create in that programme should be readable for as long as possible (even when the creators of the software are gone)
4) We the technically educated are supposed to teach the societal ramifications of certain software products as well (privacy, surveillance) and how to guard from those. So software that doesn't spy, isn't creepy and etc gets a plus as well
Students don't have a ton of money, so if there is a free and open source solution that isn't bad on quality compared to the commercial (or data stealing) alternatives, I'd go for that, because it helps with nearly all the points above.
I am however not a friend of teaching people tools they cannot use. So while teaching someone Blender instead of Maya makes a ton of sense, because Blender is great and getting better, teaching someone Cinelerra when Premiere or Avid are a much better choice functionality wise is something I wouldn't do just for the heck of it.
