Request #68096 has been Rejected by Muflone [1]: there wasn't anything illegal in the merge request, both wechat-bin and wechat used the same sources until yesterday.
today the maintainer has changed the upstream source to UOS, which is not illegal nor illecit. If you don't want to use the wechat package don't install it [1] https://aur.archlinux.org/account/Muflone/
