The privacy problem with Instagram isn't what people post on it (they want it to be seen publicly), it's what the disgusting company behind it collects in the background as you interact with it (who may be a non-Instagram user and just need to visit an Instagram link you've been sent).
People don't use Bibliogram (or other alternatives) to access unauthorized data (all it displays is the same data visible on the web or via the app), it's to be able to browse without being stalked by Facebook and avoid their dark patterns.
