But no one would force you or anyone else to leave that Apple ecosystem you hold in high regard. There would simply be more opportunity for alternatives that, if they are well implemented, may even provide such a robust product for such a long time that even devoting little energy to the decision on security grounds may make it more appealing than Apples. Or maybe some feature, such as the one I described for accessing banking institutions after office hours, might make such an impact on your situation, that you become more open to those additional choices. And if not, again, you may stick with Apple all the same.
