The developer is in China: Criminal Nation. IOW it is legally owned by the Chinese Communist Party (CCP), like everything else situated in China. I call it a criminal nation because it consistently (a) Steals intellectual property (IP) from the rest of the world (b) Uses hacks and malware to steal IP (c) Has been documented since 1998 to surveil uses of its legitimate and hacked software. IOW: The developer may be sincere, but is not. IOW: Avoid this potential malware. Sad.
