Unblock Origin is best in class for sure and I use it on my other browsers, but when browsing on Safari I don’t notice any real difference in the number of ads I see compared to Ublock Origin, that is to say I don’t really see any ads on any browser I use.
My point being that the statement that there’s “no good ad blocking on Safari” is just not true. Saying “there’s no Ublock Origin on Safari” is true, but that’s not the same thing as “no good ad blocking”. AdGuard works just fine.
Under its past owner Evidon, their business model was based on selling data to advertisers.
Starting 2018, they showed personalized ads by themselves, through the GhosteryRewards program. I think that has since been terminated, but it would comply with the FAQ you posted (they claimed that personalization was purely on-device).
I don’t know of any current offending practices, but there is no reason to trust or support this enterprise in the presence of better alternatives. uBlock Origin never did any of that, avoids all shadow of conflict of interest, and works better.
