That is literally my point. You don’t need to “block” the ping functionality (which itself would be come a fingerprinting data point) any more than you need to block xhr/fetch or following 301 redirects (which are also used for the same purposes the ping attribute may be used for) There are literally dozens of content blockers available for both macOS and iOS and all have extensive block lists of trackers, ad networks, etc. Some also allow you to add custom rules. That same content blocker will also block XHR/fetch based link tracking that many will just fallback to if ping support is not detected.
