Apple not sharing their chips extends to Apple keeping their grip on the higher density nodes.
I wonder if it's still the case, but for a while Apple was buying the totality of TSMC's capacity for 3nm nodes, leaving the rest of the world with only 4nm+ chips to grab.
You don’t need to wonder. Top of the lines Snapdragon, Dimensity and Exinos SoC all use 3nm.
Amusingly, it’s the second time in two days I have this discussion here and I have noticed that a lot of people, who I think are American and using Apple phones by default, are completely unaware of what the mobile SoC landscape looks like nowadays. Apple lead doesn’t exist anymore as of this generation.
Apple still leads in raw performance. Their M5 is far ahead of basically everything in single-core performance. AFAIK it's because their architecture prioritizes IPC over frequency, and they can spend the entire silicon budget on a very large monolithic chip.
