I live in Sweden and I would never trust any ISP. There are too many cases of data shared with "business partners" that led to things like tries to extort torrent users or porn surfers (even reputable ISPs). This should be, if not illegal at least highly problematic in the eyes of the law. At best the ISPs got a "better behave, because next time ...". All ISPs have data sharing with "selected partners to ensure service quality" which, at least until GDPR, meant basically that they could sell data. Whereas cloudflare states that the 1.1.1.1 data will only ever be shared with APNIC in anonymised form (which they define). Cloudflare defines what data they share for 1.1.1.1 users, which my ISP does not. I trust cloudflare, at least right now. If they were to change their retention policies and agreement I would maybe reconsider.
