這次的事情是 microG 的人 fork 了 LineageOS 專案，因為 LineageOS 專案拒絕 microG 的 signature spoofing patch：
Why do we need a custom build of LineageOS to have microG? Can't I install microG on the official LineageOS?
MicroG requires a patch called "signature spoofing", which allows the microG's apps to spoof themselves as Google Apps. LineageOS' developers refused (multiple times) to include the patch, forcing us to fork their project.
Wait, on their FAQ page I see that they don't want to include the patch for security reasons. Is this ROM unsafe?
No. LineageOS' developers hide behind the "security reasons" shield, but in reality they don't care enough about the freedom of their users to risk to upset Google by giving them an alternative to the Play Services.
The signature spoofing could be an unsafe feature only if the user blindly gives any permission to any app, as this permission can't be obtained automatically by the apps.
Moreover, to further strengthen the security of our ROM, we modified the signature spoofing permission so that only system privileged apps can obtain it, and no security threat is posed to our users.
於是就 fork 了新的專案... 就觀察看看吧。
