IMO that's much less of a case for laptop and desktop (let alone server). Even if people don't understand the technical details e.g. Apple's superior performance per watt (or its implications at least) is something a lot more people notice.
Intel focus on low volume high end chips is another reason they are behind.
In what way?
TSMC doesen't design or sell the chips. If they have limited capacity they will of course charge more for manufacturing mobile chips if they can sell the capacity to Nvidia/AMD/Apple instead.
ARM chips (and that's pretty much by design based on ARM's business model) are close to being a commodity.
Apple is of course an exception but they are not directly part of the CPU market. And ARM and Qualcomm are barely bothering trying to compete with them because there doesen't seem to be a lot of point. They themselves are pivoting to datacenter because there is just more money to be made there.

I guess that's complicated. It seems like an optimal strategy if you are a chip designer (e.g. Nvidia or AMD vs Qualcomm). Not so much if you are a fabricator. Of course Intel being both makes things a lot harder for them.
Like I did (at the time) high-end gaming on it, back when gaming used to sometimes tax your CPU and not only your GPU, and in that entire time I didn't ever feel like I would have benefitted at all from an upgrade, it was so far ahead of the curve. And that was AMD's budget chip line! They simply didn't deliberately cripple it nearly as much as Intel did their Celerons.
(Though I blame developers being lazy with optimisation as well as games also being released on console for this.)
