MetaMask, the popular Ethereum wallet, briefly disappeared from the Apple App Store on October 14, raising concerns about its relationship with Big Tech. Users were temporarily unable to download the app. MetaMask reassured users that this was not a security issue and its team was working to resolve the matter. The app's removal was likely due to Apple's guidelines prohibiting certain background processes, such as cryptocurrency mining. It was later restored to the App Store, and MetaMask encouraged users to report any fake versions. This isn't the first time MetaMask has faced challenges with major tech platforms, having been suspended from Google Play in 2019 for similar reasons. Apple's 30% transaction revenue requirement is also a concern for crypto firms.
