For those not aware, a few months ago after reaching out to me, YouTube contacted the App Store stating that Juno does not adhere to YouTube guidelines and modifies the website in a way they don’t approve of, and alludes to their trademarks and iconography.
I don’t personally agree with this, as 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.
Sideloading is a term that’s been around for decades, it’s not some made up word by tech giants to make people scared of installing apps.
The term originates from a designation for transferring data between physical devices and was slowly adopted (because language is fluid) to its current definition (by people on forums like xda).
This isn’t some conspiracy and Google and apple don’t need to use coded language to prevent you from side loading, apple for example just outwardly and bluntly forbids it.
