This article isn't about labor camps or the CCP's secret police. If you look at the censorship itself, the gap is much more narrow.
FB/GOOG absolutely do. You may trust the USG or the companies it pressures into this domain of behavior more than the CCP/Xiaomi (or may not - it is not relevant to this point) but the comparison is there.
There's no day in the US where remembering a day equivalent to violently pancaking protestors beneath tank treads (take your pick of our atrocities) was censored everywhere as was the case recently on the day of the Tiananmen Square massacre in China.
