I think transcription (even if not perfect) helps a lot when English is not your first language and you are still training your ear. Remember not everybody processes audio the same way, think ASD or ADD people.
The implication hidden in OP's comment is that Amazon, a multi-billion dollar company, is seeking to pay less money to people generating content for its platforms and instead provide users with an inferior product. The question was semi-rhetorical, with the understood context being that the best choice would be for Amazon to pay for all the licenses required to make their products better.
