@Ox1de Motorola Mobility and Motorola Solutions are entirely different companies. GrapheneOS isn't partnered with Motorola Solutions and neither is Motorola Mobility.
The original Motorola was split into Motorola Mobility and Motorola Solutions back in 2011. Motorola Mobility was subsequently purchased by Google in 2012 and sold to Lenovo in 2014.
Motorola Mobility owns the Motorola trademark. Motorola Solutions is a different company using the trademark under a limited license from the split.
