I personally am not very interested in this research. WeChat is well known not to use end-to-end encryption. Considering that the app is unlikely to adopt end-to-end encryption (likely due to censorship being a business requirement, which was mentioned in the article and previously uncovered by this lab), I don't really feel like I care a whole lot between good non-end-to-end encryption and bad non-end-to-end encryption. Parties that are interested in subverting this kind of encryption, such as governments, likely already collaborate Tencent to get decrypted messages from the source.
