      Normally I don't trust wikipedia, but even they describe the mechanism better than that video:

      "A marker with GCJ-02 coordinates will be displayed at the correct location on a GCJ-02 map. However, the offsets can result in a 100 - 700 meter error from the actual location if a WGS-84 marker (such as a GPS location) is placed on a GCJ-02 map, or vice versa. The Google.com street map is offset by 50–500 meters from its satellite imagery,[9][19] while the Google.cn map is not.[20] Yahoo! Maps also displays the street map without major errors when compared to the satellite imagery.[21] MapQuest overlays OpenStreetMap data perfectly as well.[22]"

      So theres a way to license the GCJ-02 algorithm (meaning its also deterministic) so map vendors can display accurate placement on a GCJ-02 map, but it probably requires following Chinese regulations. This seems like an obfuscation technique similar to how the US limits the accuracy of GPS in certain areas, for certain time periods and for certain industries, China just went the extra mile. Not exactly the hyperbole that the youtube comments for that video are screaming about.

      Interesting video, hadn't heard of this before. I think this a great example of why our response to this propaganda should be to try and understand the specifics and historical context of the accusation instead of outright denying it. More often than not these types of smears have some truth behind them but the real rhetorical trick is making relatively benign stuff seem evil just by invoking idea of communist repression.

          IIRC that is also the case in Europe. Like you need to obtain a license from the state to open a surveying company.

        I'm not sure how to even find that out to be honest. But I'd figure most nations will have some vested interest in hiding or obfuscating some geographical info from the general populace.
