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.

Do you think that Amazon couldn’t offer a sum of money to publishers that was lower than the retail cost to allow a real, accurate transcript?

The music publishers accepted an offer from Apple to allow any song from anywhere to be counted as a “purchase” for $25 a year through “iTunes Match”. There is some number between $0 and $full_wholesale_price that the publishers would accept.
