Soon after shooting into fame, ZAO started drawing flak over certain privacy-related matters.
It enabled them to use/share uploaded photos without specific consent but has now been removed by the company.
Here's what MOMO promised to address the concerns
"We understand the concern about privacy. We've received the feedback and will fix the issues that we didn't take into consideration, which will need a bit of time," the developer said while promising to alleviate the concerns and delete all uploaded photographs.
Then, there's issue with the basic nature of this app
Along with the issue of indiscriminate data collection, it is the basic nature of the app that is raising alarms.
Specifically, it is so good at swapping faces that people could abuse the program to put anybody's face in a video and spread misinformation about them.
We have already seen how Deepfake tech can be used for creating fake porn videos of popular celebs.
WeChat has blocked ZAO
ZAO remains available on Apple's App Store but China has started pushing back against the service. State-owned media is running stories about the app and tech giant Tencent has blocked links associated with the app on its WeChat messenger over 'security concerns'.
