This is not true. If I buy a Canon or Nikon or Fuji, I do not have to install any special software or mobile app in order to use it. You insert a memory card, shoot, and process the files in a 3rd party app (ACR or C1). Most of these cameras can have their firmware updated simply by downloading it off the manufacturer's website. I never registered any of my cameras but I still get warranty service if I present the purchase invoice.
DJI have specifically chosen to design their set-up workflow so that you cannot use their drones (even drones which come with a separate controller and do not require a mobile phone to use!) without first downloading the DJI app on your phone,
granting it permissions to access your data, and providing your personal information.
Yes, Adobe and (in particular) Microsoft as well as other software manufacturers are also problematic in this respect. But even they usually respect data protection and privacy rules (such as the EU GDPR). The data collection I have seen from Chinese software manufacturers is consistently aggressive, far reaching, and unnecessary.
This is not a matter of ethnicity or cultural background -- it is a matter of
political policy, where companies are expected to collect data on everyone with the aim of someday using that data to further the domestic and foreign policy objectives of the state.
And when you have a central instance dictating it be done, then it is fair to apply a broad brush consistent with the breadth of that diktat.
Similarly, the behaviours and attitudes of Chinese tourists originating from mainland China are shaped by elaborate mechanisms of opinion- and attitude-forming, mechanisms whose existence and effectiveness is openly acknowledged by all sides. This creates a homogeneity which is not seen in most other cultures.
In the past, this was used for the benefit of China: the country's incredible success is largely the product of Deng Xiaoping's magic formula of hard work and humility. Then Xi Jinping decided he knew better and replaced humility with arrogance. (The result is an economy which is stagnating so badly the Party recently had to reverse themselves and
bring back the disgraced Jack Ma to try and save the situation.)
But in this environment, it makes sense for Hasselblad to design their UI so as to appeal to Chinese amateur photographers and the political imperative to demonstrate Chinese superiority, the way Arcteryx established itself as one of the "
Three jewels of the Chinese middle class" after being bought by a Chinese company.
Anyway, we are getting rather off-topic.
