Hi Zaneo!
I’m Anastasia, an OSM communications specialist on the OSM mapping team at Lyft. 
Many thanks for reaching us.
I want to assure you that the Lyft mapping team takes the OpenStreetMap rules seriously and that all of our resources are compliant with them. As "Lyft-owned aerial imagery" for now, we use Nearmap imagery. They do allow us to use their imagery for OSM edits by license. That means our evidence fully complies with the OSM requirements. This data is updated frequently, and we try to make edits based on the most recent data. 
This information is in the description of my profile in the "Lyft’s-owned sources (ex.proprietary sources)" section.
Best regards!
