We need Linux OSes and phones to catch up to really break free from this duopoly. Only when there is enough traction, essential infrastructure like banks will start supporting Oses like that. It's a chicken and egg kind of problem.
what happened to Sailfish? the successor of meego et-al It is finnish, anyone knows how are they going? i used that for 2 years, it's linux+kde bottom to top, a terminal + shell is a builtin, though only supporting 5+ years old Sony phones got tiresome. Still.. it seems the only one that's usable enough apart of the duopoly. May have to switch to it again.
The situation with Sony Xperia devices is not great, the best experience is still on the X10III (from 2021 I think) and there are significant issues with the support of 10 IV and V generation devices (a free beta release is available for those as well).
It seems that recently there has been quite a lot of buzz in the Sailfish community compared to the past few years. In the public repos there are some interesting contributions like xdg-shell support for Lipstick, which looks set to enable compiling many previously unavailable Linux apps natively if that will actually be integrated in an upcoming OS version.
