Re-signing iOS binaries is tedious, but ultimately scriptable (including creating certificates, provisioning profiles, etc.). Android’s sideloading is significantly easier, and it still hasn’t led to anyone competing with their App Store.

Amazon at one point made a strong attempt to compete, and I actually bought a few apps from there. Also, on Android Epic made their own app store you had to sideload to download Fortnite.
