There’s not a good way to find out, no. A lot of the data is “anonymous” when collected, and aggregated before it’s sold. But it’s not hard to de-anonymize the data afterward.
So it’s hard to put together a firm trail that shows data from point A gets to point B.
I appreciate your response. it’s good to know I’m safe running what I know. And cerement gave me some good info so I can learn more about different distros. :)
