I don't even know what to make of that anymore. Just because it's self-deprecating doesn't make it okay.
I mean the tweet is putting the blame at the wrong people (it's a business decision after all), but I wouldn't go as far as call it "hate-inciting nonsense". You're not under attack.
I don't see it.
I can't think of a good reason to have a network-connected dishwasher. I don't think I'd ever start it remotely, as I still have to clear the table and rinse the dishes. The washer gets started when I'm done loading it. I can check detergent levels while the door is open.
Pretty much the same for all my other appliance for that matter.
I did see the twitter screenshots, but as I don't own the device myself I couldn't really judge if the GP's instructions are readily apparent to the average user.
Also, I don't disagree with you. But the OP seemingly bought such a device and connected it to their wifi. Maybe they are living in a furnished apartment with pre-configured wifi? Anyway - thankfully we are not yet in an era where ones only choice is a connected dishwasher - can still buy used, older models etc.
edit: One would hope that you can factory reset the dishwasher to make it forget the wifi information, if it has been configured by someone else.
It would be best if most machines didn't talk to us, at all. Press a button: it runs. Nothing more.
An appliance going "nope, I have one path for this" is, tbh, to be expected. A dishwasher washes dishes, and the idea that there is a secret-sauce way to tell it to do something it isn't actively presenting to you is not something a reasonable person is going to expect. It's why my dishwasher has like eight buttons on the top--it enumerates everything it can do. So if that appliance is hiding its verbs, then a reasonable person is going to assume it doesn't have any.
