Block all. Always.
Block all sites. Always. Caveated of course if it's a niche site that I visit for a reason because I choose to.
TBH I don't really care about "diverse" publishing ecosystems, I really don't. The publishing bottomfeeders are most likely publishing bottomfeeders for a reason and if their advert targetting systems are so good then why do I see such a layer of meaningless drivelware ad-shit spread across the entire internet that I have not one iota of interest in?
