There is functionality hidden in the app, so that the manufacturer can save a dime and a half on some buttons. Unfortunately, this line has already been crossed.
The functionality that is hidden: Rinse, Machine Care (self-cleaning), HalfLoad, Eco and Delay start.
Granted, not everyone wants or cares to minimize waste when it comes to objects of convenience, but plenty of folks want the option... and yes, I do realize I sound like "your father who bought fancy cars with manual windows because it's one less thing that can break." :) My own father was that kind of person.
I trust Consumer Reports and would never buy an appliance without consulting them, but it doesn't surprise me that they're a little conservative and wouldn't realize they need to call this stuff out initially.
We're probably all familiar with the XY problem, but I think we must also beware the XY problem-problem, where a posed problem is inappropriately identified as an XY problem and a good question is not given a good answer. (See also: much of Stack Overflow) https://en.wikipedia.org/wiki/XY_problem
The interesting bit would be to have the reaction from Bosch. They "updated" their design and the review score went down.
In the meantime "wifi" is a feature that can be filtered on in their sorting tool.
For example, the AC unit I bought, resets any settings changes from the front panel if you power cycle it, unless you configure them in the web interface.
My new microwave with a "child safety" lock has a button combination you can use to disable the lock, but it forgets that setting on losing power, so you have to perpetually keep the sequence needed around if you ever have brownouts or blackouts.
And, of course, if you just ignore it, it might be waiting for someone to come by with the right bluetooth or 802.11 network or s/t and use any "optional features" however they like...
And if the TV decided to implement weird, non-standard control signals, it can be a pain to access certain functionality with universal remotes (e.g. settings).
Different path to get there, but same end result: not being able to access functionality without going through an annoying manufacturer-specific route.
but generally a wifi/bluetooth chip isn't going to be the point of failure that brings down an entire appliance... most work without them
I've replaced a lot of logic boards and it's usually something every board needs upstream like a voltage regulator or a capacitor that brings it down
The good ones do, but some will stop working if any functionality dies. Hardest part is knowing which are which.
