The reason why platforms such as Discord, Facebook, etc don't give open access to your content isn't because they don't want a predatory ML company to vacuum up your content, rather it's because they want to sell access to your content to the predatory ML companies. Meta already trains its own AI on Facebook and Instagram user content. Discord's business model (host an unlimited amount of data for free in perpetuity) is inherently unsustainable, so it's likely they'll start selling user data to ML companies within a few years (assuming the AI boom lasts that long).
