The thing with iOS and iPhone is that it's the market that pays best. A typical iPhone user is more conditioned and used to pay for apps, and is more ready to pay for the cool factor. So, switching the target market to Android devices may be harder than one thinks.

> Qt, Java, etc.. are not updated for years.

Hmm. Have you really been paying attention? They very much are, and in exciting ways. They don't make old versions unserviceable though, and that's great.

Yes, but "things that pay best" and "sustainable computing" are often in disagreement. Nothing wrong with chasing the money, but you should be honest: "Because I wanted to earn more money, I decided to use locked-down cloud-based devices. This means my computing is not really sustainable, and sometimes required putting smartphone up the mast, but I need to pay port fees and buy fuel for my boat"

And yes, there are all sorts of exciting things in Qt and Java world, but you don't have to use them. We currently build some tools on Qt 5.9 (2017) and feel no pressure to upgrade at all. And my computer still has Qt 4.8 available (including dev headers) from 2011, which I assume still works. Which is great, I agree.
