Incidentally I've always hated Canvas and probably every other LMS provider, but what is particularly amusing about this current outage is that it is occurring at exactly the time when universities are demanding that all professors put all of their materials on Canvas, without exception, due to ADA compliance regulations. It is explicitly forbidden for professors to, e.g., refer to pdfs posted on a personal website.
Other commentators here seem not to understand that many faculty also do not enjoy being forced to use Canvas.
The MS services have not improved teaching at all. What they do, is fragment communications, and add ever more places people have to look, in hopes of finding things.
But the administration loves them. "The bureaucracy is expanding, to meet the expanding needs of the bureaucracy."
Thankfully, I store my teaching materials on my personal non-uni webpage, and the student's marks in my office's computer (apart from the MS-based Uni system).
Whenever something happens with MS, chaos ensues throughout the whose Uni and the students end up paying the consequences.
And of course the other serious concern I have with Canvas is that they are likely using all the materials faculty upload to train their AI replacements. Many of my colleagues engage in dark humor about this but I haven't noticed much action.
Instructure (Canvas's developer) partnered with OpenAI last year [1], about a year after KKR and Dragoneer (PE firms) acquired it [2].

I would guess these plugins are chosen so a majority of user won't want to live without them.
It also seems these plugins "link" to canvas-lms, so keeping the proprietary would be a GPL violation if anyone except Instructure holds part of the copyright to Canvas.
That calculus is about to shift.
I'm not sure where your stereotype even comes from, because Canvas is not trivial software. You can see for yourself as it's AGPL and I assume you looked at the code before criticizing it because any good engineer would do that.
It's been long enough that I can't claim to be in touch with the current generation of teaching faculty. But it might be an element of that, combined with the desire to provide accessibility for the handful of students who do in fact need the accommodation.
The administration has so far opened with one “Canvas said” and then an hour later one “Canvas is down indefinitely” email noting that they’re aware it’s serious.
(Canvas is a glorified wiki for teaching students, with quizzes and such, for those unaware.)
That's my biggest fear.
Note that little of this really helps the students that it is supposed to help, because as you wisely point out, raw HTML is almost by definition extremely accessible. I work in a field that uses Latex and the source code of Latex should also be considered more accessible than the compiled pdf. But for university administrators the only important thing is that the accessibility metric that appears (or used to appear, before today!) on Canvas shows 100% accessible.
Nobody has infinite energy, and disabled people don't have infinite social capital. It's a shame when energy from that shared pool gets spent on things that don't really impact meeting people's access needs.
And the other thing is that everyone's access needs are different. It can certainly be useful to try to set a baseline or propagate common guidance. But the most important thing, especially in a university setting, is for instructors to be flexible and responsive and for classes (and non-teaching workloads) to be structured in a way (e.g., small enough) that supports that.
I think metrics like "100% accessible" might even be dangerous. It makes it easy for able-bodied people who aren't in direct contact with disabled stakeholders to pat themselves on the back without actually knowing what's going on.
Bleh. Good luck doing right by your disabled students and disabled colleagues, and good luck resisting the bullshit.
I'm a prof. When I have a student with special needs in my class, the administration tells me ahead of time. I make the necessary allowances - and those differ from case to case, anyway: whether it's extra time in exams, or someone who is deaf, or someone who is blind, or whatever.
When it happens, I make the necessary allowances. When I don't, then...I don't.
The obsession that everything has to be 100% accessible, for every kind of disability, all of the time? That's just nuts, not to mention a complete waste of resources.
