Yeah, that's been a problem lately. Haier also recently issued a takedown against the maintainer who published the Home Assistant integration for their brands of air conditioners and other smart appliances.
Ford, Tesla, and several other smart device makers have similarly taken their seni-open APIs to license-only/closed source only recently.
Which is dumb because even if they DO want to monetize that data stream by selling it to data brokers, the people they've affected by closing those APIs represent a small fraction of their user base. It amounts to a rounding error in the revenues.
