If you have a risk of getting sued because someone notices a transcription error versus just not uploading videos, people will choose the latter.
A common compliance mistake (for any type of compliance, not just ADA) is:
* someone tells an SWE to implement [compliance measure]
* they implement poor quality [compliance measure] that doesn't actually meet the compliance requirement, close jira ticket
* they don't realize they didn't meet the compliance requirement because they don't use or need [compliance measure] and they are a SWE without any expertise with the law or the understanding of reason for the need for that requirement
Now if you are talking about the blind then sure thats different but the blind don't need captions.
What if they are hard of sight and can't read the whiteboard or blackboard, even if they might be able to read a captioned video?
Lord knows I remember barely being able to read some professors handwriting, even in person, or being able to understand what the hell a professor was saying in person.
How many people are there that can efficiently caption complex mathematical equations?
