No software solution for stupid
Well, there is, but the solution may actually be worse than the problem, in some respects. It involves treating all users like children, penning them into a walled garden, and "protecting" them from things that are, in many cases, not really dangerous at all, but are just in conflict with the vendor's attempts to sell your soul to the highest bidder.
Oh, and some are legitimately dangerous, which makes a fantastically convenient pretext for that nice big wall.
And ... it turns out the this wall doesn't actually keep nasties out after all, but just ignore that and look at the Wookie!
The result is that the rest of us suffer restrictions imposed for the sake of, erm (how shall I put this kindly?), the Great Unwashed, who frantically click on all manner of shite, without the slightest care in the world about such trivia as user reviews, provenance or developer reputation, in a seemingly desperate bid to stuff their devices with as much malware as possible.
One of the more annoying consequences of this mindless stupidity is that people like me, who root their phones to be able to do a few things that might actually be useful for a change, become technical pariahs to the likes of banks and, much more bizarrely, as I discovered quite recently, bus companies.
Yes, rooted devices are blacklisted from viewing a fucking bus timetable.
So, to the idiots of the world, I'd just like to say a big "thank you". You bring joy to my life.
