This is an avoidable mistake, but I think Apple and Google need to take the responsibility of their users not to download fake apps on their stores. There are many bitcoin users that do not even know what verifying of wallet signature is before using a wallet. But if they do not know that, they should know that they should make investigation before making use of a wallet. If Sparrow is now on App store, it would be seen online through search and also seen on their office website.
It’s an avoidable mistake for those who know how, are cautious and curious about these things. There are a lot of forks out there that haven’t got a clue on how to verify or the need to verify these wallets before download. These are the ones that depend on Playstore and AppStore to have down this for them, given the huge company name and what could be gotten out of them. They directly occupy a position of trust for most of their users and this trust is being bridged due to the poor verification or promptness to take action when these apps are being reported.
I am of the note that we are our first line of security but, these companies need to do better, at least when these apps are reported through the proper channels and with evidence.
