Example, purely hypothetical for this scenario, but based on a real experience I had recently...
What if there was a data source that went into this from a third party? What if that third party had requirements about the timeline of removing data? This could be because it contained user-generated content and something was found to be offensive or even illegal, or it could be because it contained something proprietary that needed to be correctly licenced, all sorts of possibilities.
If you provide a data dump, you then need any integrators to add a data refresh process. That's an additional step that many won't do. Now you can't honour contracts or potentially legal requirements.
Sure you can document this, sure you can put it in contracts, but that may not be enough.
