Jokes are usually deleted by mods. But I noticed if the mods like something, rules don't matter.
Basically HN in a great place for techie jokes that are essentially unique to this one tiny corner of the internet. The 4 or 5 we get per year are often some of the best content.
It this case, the criticism was, Apple products will narrowly optimize for something pleasant (well-restedness) at the cost of what you really want (getting to work on time). This is a very common complaint[1], and it's kind of witty to joke about them doing it by accident here, when it's what they deliberately do in other contexts.
[1] Examples: making the URL bar look nice and minimal at the cost of you knowing where you are in a site, removing the scroll bar at the cost of knowing where you are in a page or how to move it, making the mouse unusuable when charging just so you don't have a hole on the top.
HN is a an uncanny reflection of the tech sector in its current state, same people

Most of the HN guidelines are subject to a fair amount of human interpretation.
