I doubt xiaomi and other Chinese company dares to enable censorship anywhere in international markets, or have a secret plan to control world's information discourse to support ccp. Any censorship or apparent support of ccp will be caught within seconds. Its commercial and political suicide. Also if they do have a secret plan, just blacking out whatever people are typing on their phones is such a dumb, stupid, and crude way of implementing censorship.
Also, this report found no censorship mechanisms on huawei and oneplus phones. Yet they said people should ditch all Chinese phones, which implies all phones originated from Chinese origin companies have censorship mechanisms. That is a much larger conclusion than what the evidence they provided, seem like a politically motivated desire to discredit and defame all Chinese origin companies and products.
I also doubt ccp has a marching order for Chinese companies to censor speech internationally and manipulate world's information discourse. Chinese phones have big market share already, and huawei's gear has wide market share in Europe, but no one ever experienced censorship on their device for speaking against China. And if there is a secret plan to control world's information, they are doing a terrible job at it. The covid origins, xinjiang Uyghurs, Hongkong. The point of view of Chinese side is non existent. For example the xinjiang Uyghur situation, I know people in xinjiang, many of whom are uyghur people, the accusation of mass genocide, 1 million imprisonment, wide spread physical abuse and rapes in prisons, massive internment camps with forced labor is wildly inaccurate from the truth. Yet, it hasn't stopped this from becoming the wildly believed truth, to the point where if you disagree with these statements, you are a ccp shill, a genocide sympathizer and brainwashed. For me and a lot of mainland Chinese people I know, we feel our voices and our personal real life experiences are being censored by international media and public discourse. Sometimes I read something about China in the international discourse, it feels its talking about an alternative universe than my real life experience. I have to wonder who is really controlling the narrative, censoring speech and pushing their political agenda.
