Add Haier to the list. They’re threatening Homekit devs and issued a takedown on a GitHub hosted HVAC controller for their units. Citing it hurting their income (I assume they mean data mining income when you stop letting them monitor your appliances online).
The dev is looking for a lawyer to consult, and wants to fight, so has probably not got any copyright infringing code in his repo.
Oh and for boycotting purposes, they sell appliances under the brands: Haier, Casarte, Leader, GE Appliances, Fisher & Paykel, Aqua and Candy.
