Lawyers have little issue defining blogs like mine as "with commercial interest". I have a side-business, so lawyers could make the argument that I use my blog as advertising. I have a Ko-Fi link in the bottom of one specific site, that's a commercial interest, too.
Unless your blog is "I'm sharing holiday photos and nothing else", there's a lot of instances where it could be define as an outlet with commercial interests.
And, ultimately, I have no desire to spend any time and money on fighting even completely invalid claims. I'd rather spend my time watching cat videos on YouTube instead.
But their licensing doesn't care about commercial interests or lack of there of.
It only reserves right to charge you if you ship a product. And by product they most obviously mean a device and by ship they obviously mean sell (or gift, or possibly rent) to some customers.
All of this sounds like a thunderstorm in a glass of water by people who read too many software licenses.
It's because people read more than one sentence and the very next one is:
"Failure to maintain active Thread Group membership while shipping Thread technology may result in legal action, including but not limited to licensing fees."
Which specifically mentions legal action in reaction to shipping only.
"Membership in Thread Group is necessary to ..." is just a statement of their wishes.
It's like "Sleeping is necessary for good health". It doesn't mean we'll sue you, if you don't sleep.
