Sadly, the current popular &#x27;solution&#x27; to this problem is for massive centralised gatekeepers (Google&#x2F;Apple&#x2F;Microsoft) to control software distribution, and to varying degrees prevent you from installing anything that didn&#x27;t come from their store.<p>This undeniably makes security easier for non-technical users, but I hardly need to point on the downside on HN: these companies get to decide what programs people can install and distribute to others. They&#x27;re not held to the standards of governments like due process and accountability - even though there are probably now more Android users than citizens of any one country [1].<p>Kudos to anyone working on alternative ways to make security easy without these gatekeepers.<p>[1] 1.4bn Android users in September 2015, according to Techcrunch, vs 1.38bn estimated population of China in 2015. Android is growing faster.
