I still don't understand why it's a problem for those who publish the data.
If the "data" is facts (e.g. lists of values associated with objects, like the colors available on automobiles), this data is not protected by copyright, there is no remedy if it's republished, and if a business relies on limiting access to this data, that business needs a new business plan. Charge for access to cover the costs of obtaining and organizing the data, but understand that clients are legally allowed to make copies and use them however they see fit, even if that impacts the supplier's ability to charge for access.
If the "data" is prose, it's under copyright and republishing without a license has remedies under law. Maintaining copies of articles for the purpose of processing them to obtain other data (e.g. how many nouns? what adjectives are near those nouns? etc...) isn't protected.
