This is something that the amazing Naomi Wu brought up for years before, and was ordered to stop publishing by the local government. It was about the same thing. It’s sometimes misrepresented as being about Signal, but her point was: There’s no point in using a secure messaging app like Signal if your keyboard (IME) leaks everything you write! So she was making the exact same point as in this article.
I really miss her content. 😢
Yeah she clarified that literally, it’s not linked in the article.

I can’t find the source of her saying it was about the IME thing but I recall reading that from a person close to her. She had just raised it before all this happened. Edit: Oh wait, that’s here: https://skepchick.org/2023/08/maker-naomi-wu-is-silenced-by-chinese-authorities-and-why-i-blame-elon-musk/ (This was linked on wikipedia)
And yes she’s a great person, she was often criticised for being a CCP stooge but that was BS. She was as outspoken as one can be being in China (and unfortunately, clearly a bit more than that).
