Thank you for most of the points, it's easy to miss the good parts of development of the recent years.
I don't however agree with this one: "It will take a few years, but I'm sure we'll have a viable alternative to Android in the near future." I think many essential apps (such as banking, or "less essential" such as for bike- and car-sharing) will start requiring device attestation as soon as even low-end Android phones start shipping with hardware TPM.
Yes, I agree that this will be the critical point, but ... it all depends on the critical mass of users. About 20 years ago there was no CAD software for Linux, no IDE for rapid development and now we have tons of incredible tools in all areas: FreeCad, Blender, Lazarus, KDevelop, QT Creator. JetBrains produces incredible cross-platform development tools.
The same revolution that happened on the desktop can happen on mobile. The people at Pine64 are creating incredible and affordable devices, and this is just the beginning. The open source revolution is spreading from software to hardware (Risc-V processors for example).
In my lifetime I have seen Linux and open source software in general make incredible progress. And it is not only a technical aspect, but also a different way of living and seeing the world: hundreds of thousands of developers working together for the benefit of the most, beyond any language, geographical or political boundaries.
It also depends on the choices that each of us will make to stop supporting and encouraging predatory and monopolistic regimes, and instead make choices to preserve our freedoms as individuals, which are more important than the last "nice features" in expensive and proprietary gadgets that imprison us and our data in closed kingdoms.
Oh, I have a nice contribution to your comment! I use some taxi apps (very infrequently), and sometimes I need to call it for someone else, not in my current location. Sometimes there is a promotion catch with, say, 20% discount. Which is applicable only for a personal ride (e.g. from your location), but if you ask a taxi to bring someone to you (e.g. from other location to your location), well, then sorry, not applicable. I used to trick the app but faking my location on my Android with gps-fake app (don’t remember the name, mine was from f-droid). I bet taxi services are not happy about that kind of a customer. Giving it some thought: still a returning customer. Sometimes it’s not just the money thing for me, but the challenge of whether the algorithm could be tricked.
