That only works when there is an "open" that is in competition. iOS is certainly the most closed platform but Android isn't really open enough to be competition. Microsoft is making their platform more like iOS and Android every day. Linux on mobile is a non-starter as usual. The fact that the past played out a certain way is no guarantee that it will play out the same in the future. I kind of agree on being a mostly single-stack developer. I dabble in C, C++, C#, etc and I'm perfectly ok with using very different platforms for very different problems. But using very similar platforms to solve very similar problems feels like a huge waste of time and mental effort.
