They don't kick you out for buying too much though...they kick you out because you're an asshole who is annoying everyone else or outright endangering them.
I mean, that's pretty on par for other manufacturers, rule of thumb is about half of rated range during winter. It's not really the manufactures fault that part, the WLTP standard they have to use is just using a way too high percentage of steady-speed city driving to give a good idea of real-world usage for most people.
How are you able to obtain certification with aliexpress suppliers? They generally can't provide proper (trustworthy) documentation that they comply with standards, so your certification and compliance chain is broken.
Literally no one does it like that...no one. You place an order for something that's backordered, they also don't charge you until it's shipped, and you won't get notified beforehand either.
Most people will opt to buy the less expensive one every few years, either for economic reasons, or because they feel that it is a better deal to replace the $400 fridge every five years than to pay thirty times the price for a high-end/professional unit.
Unless they live to be 170+ (assuming they're 20 when they buy their own fridge) the $400 one every 5 years is definitely a better deal than one that lasts a lifetime and costs 30x as much.
You're using redundancy and backup synonymously, but they're not. Raid 1+ absolutely provides redundancy, you are 100% wrong in saying that it doesn't,, because it provides a failover system that prevents operational interruption if a drive fails.
"Over serving" laws let's them cut you off for being too drunk, not for buying too much.
