User2288 whats is the MASSIVE threat that I am facing?
Random persons can know what apps you have installed, your device model, etc. Its not MASSIVE though, but you dont want Strangers knowing which apps you install on your phone.
User2288 how exactly this is a "big problem"
Certificate pinning is a feature that reduces the risk of a man-in-the-middle attack, compromise of certificate authorities, mis-issuance of a certificate. Not implementing Certificate pinning in Aurora store actually makes sense, since We can't expect Aurora store developers to decompile every new Google Play store version and Check Its NetworkSecurityConfig to check whether Google has added or removed an certificate.
