I understand it perfectly, if american companies harvest their data, their govt is only a step from having it, and companies over here have immediate use of that data.
If the chinese companies have it, the chinese govt has it, and then what? Is china gonna prosecute us internationally with the info? At minimum they are making the US companies and govt crawl to china for the data they so desperately want.
Like, the US gets more use of data on US citizens than China would. Maybe if the concern was improving the security of american apps and data I would see the point, but seeing how many american companies continue to get away with it, it is blatant "America Good, others Bad"
