I think this is special pleading. At the volume we're discussing a surface mount flow solder on off device is not going to kill the BoM, and could be designed not to be ugly.
It's no different to any other bad design. It could be better.
All phones and computers can be completely powered down. They're hardly ugly switches.
Ermm, most phones and computers cannot be completely powered down. Either by nit-picking (CMOS clocks) or soft-switches (ACPI, soft button power-on), there's always some voltage in the system unless your PSU comes with an actual hard power switch (and even then, again, CMOS).
They consume a lot less power, but leave an 'off' phone in a drawer for a month starting at 100%, it will not be 100% when you 'turn it on'.
In low-power mode even those microcontrollers are using just nA (yes that's nano-Amps). Vs 100's of mA in operation. So the battery life goes from hours to what should be decades.
I'm thinking the battery goes dead because of leakage currents through the rest of the circuits, which were probably not designed to the nA standard.
A solid-state Off switch would also need a good silicon device to cut current consumption at the battery. Which also costs something.
This is an emotional, low-quality response to what is a measured comment actually providing nuance to the discussion.
The parent poster is very clearly not saying that leaving off the power switch leads to a better experience for the consumer - they're just giving legit reasons that a design/marketing team might use to justify doing so. Please don't try to cheapen the knowledge that they provided like this.

iPhones (and I assume most Androids as well) can't be completely powered off. Neither can Macbooks. In fact, I'd guess that most modern digital things with non-replaceable batteries can't be powered off.
There’s a specific Dell laptop reset procedure that requires you to open the case and disconnect the battery so you can then press and hold the power button to get it to discharge all residual power. It’s a pain.
I had to do this a couple of times with a Lenovo that sometimes locked up completely when it went to suspend - battery was highly inaccessible so it was a 30 minute tense process each time - firmware update eventually solved the problem. Not sure what the solution for this is - something like one of those paper clip reset holes?
