They made a mistake with that joke, but it was an outlier. I used Lineage (and Cyanogenmod, its predecessor) for six and a half years straight and never had any reason to doubt its quality. The long-term security updates alone make it one of the best options for keeping your Android device solid.
I'm definitely looking for an OS to move to from Android. I suspect Librem will have its own flaws, but they inspire more confidence in me than my first impressions of LineageOS from their website.
