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)
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)
