Net Neutrality is the reason the Internet has driven online economic innovation. It protects our right to use any equipment, content, application or service without interference from the network provider. With Net Neutrality, the network’s only job is to move data — not choose which data to privilege with higher-quality service and which to demote to a slower lane.

This would be the same for APIs, which are too often driven only by business when investors strategies come in the place. Stay open for an API without discrimination and tiering on data access and re-use is giving trust to all your ecosystem for building future business on it. Don't respect it is enfrenging the API neutrality concept.
