Instagram stores your posts and their likes and comments on its own servers, so you can't take that engagement data anywhere else. Platforms own the metrics tied to your content, not you.
Think about Instagram, for example. Why can't you take your picture or your video and take all the likes that it has on it and all the comments? Why can't you transfer that to X? Why can't you transfer that to TikTok? The reason you can't transfer it is because Instagram has a centralized world to where it contains all of your data and your value within only their server system, and it's not shared anywhere else. It's a centralized world.
