At this point I'm convinced that there's something deeply wrong with how our society treats technology.
Ruining Android for everyone to try to maybe help some rather technologically-hopeless groups of people is the wrong solution. It's unsustainable in the long run. Also, the last thing this world needs right now is even more centralization of power. Especially around yet another US company.
People who are unwilling to figure out the risks just should not use smartphones and the internet. They should not use internet banking. They should probably not have a bank account at all and just stick to cash. And the society should be able to accommodate such people — which is not that hard, really. Just roll back some of the so-called innovations that happened over the last 15 years. Whether someone uses technology, and how much they do, should be a choice, not a burden.
