In this specific CamScanner context, I think it has less to do with political correctness and more to do with the fact that CamScanner was one of the first apps in the marketplace that had this ability to produce half-decent scans through a smartphone camera. I remember using it to scan class notes ~6 years ago, long before Google Drive shipped it as native capability.

Indeed, if my social circle's "woke" parts are anything to measure by, active efforts are being made to find alternatives to made-in-china products. Most people are able to make the distinction between the despotic Chinese government and the average Chinese citizen.

Being wary in part or in full because an app or is owned, operated, or developed in China is where you run into issues.

Being wary because you find Tencent specifically untrustworthy is fine.
