In the context portion of the community note, there’s a link to a NYT article about the shady funding of one of the board members of Code Pink and a big donor to anti-war protestors like them.

He claims to not work with/for the Chinese government but from the article:

But Mr. Singham, 69, himself sits in Shanghai, where one outlet in his network is co-producing a YouTube show financed in part by the city’s propaganda department. Two others are working with a Chinese university to “spread China’s voice to the world.” And last month, Mr. Singham joined a Communist Party workshop about promoting the party internationally.

I can’t tell, and none of the articles I’ve seen about this mention, if these protestors were Code Pink or one of the groups associated with Sigham.

EDIT: I want to make clear, I’m not trying to justify or support the article or the shitty person who originally tweeted it, just pointing out the context for the actual statement Pelosi made about going “back to China where your headquarters is”

So, question of if they’re safe or not will come down to HOW they did the reverse engineering. If the same engineers that delved into the jailbroken iOS devices are the ones that wrote the code (which seems likely given the prototype came from a single person), they’re going to be in trouble. If they implemented a “clean room” reverse engineering though, then they’re likely safe from being sued over copyright violations. See Wiki
