I still don't understand why the trustwallet folks claim that their wallet is open source even on their website  and yet its only the iOS version that's open source. It's misleading since the Android version probably has even much more users than the iOS version.

It has come to our attention that some dishonest developers have been cloning Trust Wallet and either scamming users or using the code without permission as their own product.
