on mobile so can't provide source but look up why privacy badger no longer uses a dynamic "learned" list of trackers to block, the way you mention safari works and instead uses a list that everyone else uses. it basically reduces privacy because your list of blocked sites is likely to be unique among other users (along with other data points) and unintuitively makes it easier to track you across the web.
