Appliances giant Haier reportedly issued a takedown notice to a software developer for creating Home Assistant integration plugins for the company's home appliances and releasing them on GitHub.
The mistake is forking and hosting it on GitHub. If Haier sends GitHub a DMCA takedown notice, they will comply, and the forks will be deleted too. Use other hosting services for redundancy and keep a local copy.
Good point. Nothing in the article explicitly states that it's a copyright claim, but they do mention "protecting... [their] intellectual property". In any case, it's always easier for the website host to fold to cover their own asses than to continue hosting the content.
