I am not sure if you are trying to come off as snobby, but that's how this reads.
This 'class of users' is in many cases very technical people who just don't want their phone to be anything other than an appliance. It's quite common to love tinkering with things, while not wanting to tinker with everything.
Highly technical people may choose an information appliance as well, and that's fine! All the more reason for such a thing to exist.

Apple is more like a television manufacturer that only lets you watch Disney+. The extent to which they protect their walled garden is not for the benefit of the consumer.
PCs are hackable by design. It's a perfectly mainstream thing to build your own PC from parts. Hacking toasters, on the other hand, is not mainstream. Best Buy sells toasters, but not parts for toasters.
I personally wouldnt draw the line between information appliances and computers at whether the manufacturer actively blocks you (as Apple and John Deere do), but rather at some combination of what the intended purpose is, and whether hacking and customization is considered mainstream or fringe.
Hacking toasters and dishwashers and microwaves and refrigerators is possible, but fringe. Hacking cars and houses is mainstream.
Is it? Most PC (or notebook) users buy whichever one is on sale at the store, or they use one provided by their company. This does not strike me as inherently different to how people buy toasters or dishwashers.
Of course, there does exist a niche of people who like building their own PCs, but this does not imply that this is the mainstream case.
I have an espresso machine, and you need to calibrate the pressure, the temperature, clean all the parts regularly (far more than a pod machine), you need to fill the coffee grinds in a way that is distributed so the water runs evenly, you need a coffee grinder that makes less-coarse grinds, etc... its far more work, but the coffee is exactly how I like it.
And honestly, I don't think information appliances are a bad thing to have in the world. It's not the kind of device I would choose for myself, but there's a class of users for whom a general computing device isn't just overkill, it's downright dangerous.
Android is fine for my use case, and while there are specific policies I wish Apple would change, I don't begrudge them the philosophy.
