Juno is just a web view, and acts as little more than a browser extension that modifies CSS to make the website and video player look more “visionOS” like. No logos are placed other than those already on the website, and the “for YouTube” suffix is permitted in their branding guidelines.

I stated as much to YouTube, they wouldn’t really clarify or budge any, and as a result of both parties not being able to come to a conclusion I received an email a few minutes ago from Apple that Juno has been removed from the App Store.
