FWIW I got a Huawei phone (Honor 10 Lite) for under 200 EUR, but much cheaper phones than that are available.
Edit: To be clear this is not to avoid Chinese surveillance. That's unavoidable whatever you do because China is a police state. It's to separate out that surveillance from my contacts and my regular life at home. (I also think it's at least arguable that the Chinese government has a duty to look closely at what foreigners are up to. It's not an argument that I agree with myself very much because it infringes freedom while also making the wrong trade-offs, but given we live in a world of nation states it follows logically from that.)
Huawei is likely one of the companies that contributed to this very Xinjiang endeavour [0].
Even if it's not directly related, by buying a Huawei phone, you are voting with your money to support a company that's been hurting innovation with IP theft through the years [1].

The article you cite just says that they supplied networking equipment, how is that different than, for example, U.S. conecetration camps using Dell laptops? Would you also blame Dell?
I swear whenever China/Huawei is mentioned on HN, the comments transform into a huge propaganda machine.
