The blog is premised on the idea that Apple and MacBook are not doing fine.

that they're not doing fine software-wise

And nobody else is doing better software wise because Apple is secretive about how to program the hardware. Asahi is not sufficient.

The reason of course being the awful software, not the hardware options. He makes that abundantly clear in the text.

You missed my point, the original comment is stating that the market for such a device doesn't exist because developers are too finicky and customisation focussed.

As a counter example - look at macbooks which are about as un-customisable as they come, but a large portion of developers use them. Meaning the market exists even if it's currently dominated by Apple (which as you/the post points out is slipping)

Not everybody use/choose macbook though.

Having said that I do believe that many brands have way too mamy SKU and I widh they would be more opinionated on what they believe is better for their customers while maintaining clear and strong ethics (reliability should be #priority)

I don't recall saying everybody?
