Producers would use this service over others to ensure that the content that they sell is not tampered with, not censored, not edited, not removed by someone else. They would use this service to be sure that their content got to the consumer in its pure form.

Consumers would use it for the same purpose: they use it to ensure that the content they are viewing is exactly what the producer intended. Consumers would also use the service to acquire content that has been wrongly-suppressed elsewhere.
