If any appliance manufacturer says that accessing your own appliance (that you own) outside their software ecosystem is financially "damaging" to them, they might as well be saying "Hey, just so you know, we're collecting and selling your data." If you have already purchased the appliance and their software is free, there is absolutely no other way that using a 3rd-party application could damage their bottom line.
Thanks, Haier, for letting me know never to purchase your products.
