The problem is that non-smart stuff (or at least stuff that doesn't require a cloud connection) is hard to come by. For example:
cars - (nearly?) every EV and most other new cars connect to the cloud for no good reason
TVs - can't find a "dumb" TV in the 50"+ category; I'm still looking...
refrigerators - "dumb" fridges still exist, but there's not a lot of variety; we wanted a French door fridge, but couldn't find one without the smart crap with the ice maker in the freezer section (an ice maker in the fridge is just asking for problems); we had to get a side by side
lightbulbs - at Home Depot, I could only find the crappy store brand or their smart bulbs, nothing in between
And so on. It's increasingly difficult to find decent, long lasting stuff. Almost everything is going to be incredibly insecure in 3-5 years once software support stops, and then it'll be irresponsible to keep it any longer.
At this point, I don't think you can really blame the consumers, manufacturers seem intent on driving this "smart home" nonsense. Sure, have a tier for that product, but also sell a version without it.
