The day I join crypto currency mew was the only wallet I no, immediately i know of other form of wallet, I deviate from using mew currently i use imtoken, metamask and coinomi.
Since day one MEW is the only I used and up then I guess this is the only I will be using. It ain't the fault of MEW, if users are installing something not even related to MEW and that was the cause of all these, it ain't the fault of MEW. You trust a browser then then that's the users fault now. They should have been using the MEW the better way such as downloading it and use it offline.
proven and tested MEW that is why more and more this is what they may recommend also to use but always check and careful on the private key of it this is really important of here.
