They write: "I think the terms and conditions are an attempt at corporate ass-covering rather than something sinister: the preceding paragraph talks specifically about when 'a product with voice recognition functionality is used' and it's possible that 'family members, guests, children, and bystanders" might be overheard; if you're choosing to activate AI-based voice features then of course voices are going to be captured and processed in order for those features to work.'"
All of this is sinister. Opting you in by default to being spied upon is sinister. Using Windows updating mechanisms to automatically install adware is sinister. Designing features on your TVs and monitors that will violate eavesdropping and wiretapping laws unless the end user seeks consent from those present around the (some people cannot ever consent!) is sinister.
Note also that this doesn't just affect new monitors and TVs. The Gamer's Nexus video linked in the article (https://www.youtube.com/watch?v=Q9uefFYe6bM) also notes that a Windows box with a 3-year-old monitor plugged in suddenly received the adware.
