My point being, if your thesis is that releasing incremental updates is a long term problem for Apple, then you should be able to identify a competitor who is releasing non-incremental updates.
1. Someone will out-innovate them.
2. Their products and services become less relevant or obsolete.
What would you do differently if you were running Apple?
I much prefer that over Microsoft's way of adding a new UI that can do less than previous iterations, while also being less performant and tons of half-baked features like their newly-planned Copilot, still unfinished Android subsystem, worse search, etc.
Of course, neither approach is perfect, but I actually prefer system that change little on the surface and mainly adds small, but well-integrated features over time. Not saying Apple is perfect (there's tons that could be done regarding user freedom on iOS, backwards-compatibility and gaming), but neither are the competitioners.
As others say, what's the number 2 option? My number 1 for a smartphone is the Poco/Xiaomi line, but iPhones aren't that far off. Poco/Xiaomi, Samsung, and Huawei are happy to enshittify themselves, while Apple charges high but doesn't disappoint.
