While the no-logs policies of many of these providers is mentioned in their EULAs, there's never a mention of paid access to NetFlow data, which can be used to link public flows to the IP addresses of users.
Is this a thing? I recall hearing about it around two years ago.
Something along the lines of "ISPs Give 'Netflow Data' To Third Parties, Who Sell It Without User Awareness Or Consent" [0] or "How Data Brokers Sell Access to the Backbone of the Internet" [1]
