I work in a research institute that is government-sponsored, and I can assure you that our work relies on having access to censored foreign sites (Google, Google Scholar, etc.), and there isn't an official way to do so and we all use third-party or self-hosted VPNs.
All my friends and families always discuss incidents in the past history of PRC freely, and never have to worry about being surveilled. It has recently bothered me that the western media often see the issues in colored lenses, have strong beliefs in anti-China sentiments and yet provide no direct evidence relating to the claimed atrocities commited by the government. I tried very hard to find actual direct evidence and to justify their claims (e.g. [1]) but discovered none. The lack of evidence make those hard to believe and would urge you to take those with a substantial grain of salt, and not everything is abysmal in China.
Conflict of interest: I am a Chinese and I studied in the UK for 8 years.
