Yeah righty, that’s like trying to stop the ocean with your hands. You know that 99.999% of users will have several applications or gadgets forcing them — and eventually you, if you want to remain socially functional — to install an unrestricted alt-store.

Eg: anecdote: mother-on-law was gifted a cheap smartwatch (Samsung I think). Installing its companion software required downloading and registering to a whole new store on her Android smartphone. Weirdly enough I think it was also a Samsung, already had 2 stores (the Samsung and Play ones), yet she (we) had to dump yet another one on that sorry mess.
