Or perhaps the business couldn't afford transcription/translation. The GP seems to suggest it's "trivial" to add subtitles. Great! What happens when those subtitles are terrible quality? The goal post will get moved further and further by those in charge until you need professional grade transcription. If you're a small enough business you probably don't have the XX,XXX in legal capital to fight a firm that can throw XXX,XXX in to prove their point.

The problem isn't how easy it is, nor how we should do this. It's that someone has a gun to every small business' head telling them to spend money/time/resources on something they may not have the ability to do immediately. No one should be able to tell me how to run my company, or my life. It's up to me to decide to be compliant to accessibility and if I don't it may cost me customers. It's not like handicap ramps that save people's lives in fires. This is a transcription. Ostensibly not NEARLY as important as other ADA regulations. But because of it's ambiguity and relative ease to determine who and who isn't following using data miners it's a cash cow for legal vultures.
