@dansup Not sure why Facebook cares so much. For larger advertisers, this change matters quite a bit as it will forcibly change their marketing strategy, but for smaller advertisers, there's already a workaround that still allows tracking events. The difference between the two is the limit to only 8 trackable conversions per website, instead of a previously unlimited number. It doesn't protect user data as much as it limits the number of actions on a website advertisers can track.
