How does their content get on google's servers?
And last time I checked, there was no content-scanning feature implemented in Android (and especially not in Graphene, Calyx, Lineage, or what ever.)
Same way it would get onto Apple’s servers: the customer chooses to upload it.
The difference is that with on-device screening, Apple wouldn’t have to take delivery of CSAM to detect it, and it doesn’t have to scan anything that’s not destined to be uploaded.
It's all good though, I'm still using an iPhone. But might switch, especially with so many people in HN comments telling me that Android would scan all my data and send it to Google without being able to substantiate that claim.
Mine doesn't.
