It's like the situation with HIPAA rules in electronic health records: It wouldn't be impossible to write your own EHR system but if you do you have to spend a lot of money proving it meets HIPAA regulations or accept substantial liability. So companies just pay Epic $$$ because they promise HIPAA compliance.

Likewise with classroom software if you just use the "industry standard" enterprise crapware you've outsourced the accessibility liability to somebody else. If the software is hot garbage from a usability perspective, that's irrelevant.

And this is why we cannot have nice things in the enterprise space.
