@pluralistic @mozillaofficial Apparently it has to do with CCPA’s definition of “selling data” which simply includes data being transferred to any third party for any reason. Because Mozilla uses tools for collecting usage metrics and has some marketing and tracking stuff built in, any third party involved in this would receive this data, and the CCPA considers this “selling data”.
It can apparently be so over-broad that service providers have included this kind of language simply for your data being hosted in their services in a third party provider like Hetzner, AWS, etc.
So it appears to be some potentially over-broad definitions in law.
