"we don’t need to know a lot about you to deliver a great experience on Apple Maps." -> so you still need to know a little about me ?
"Even if you choose to sign in, Maps keeps your data in sync across all your devices using end-to-end encryption — so where you go isn’t associated with your Apple Account at all." -> looks like magic, data is synced accross all your devices but without using your apple account ...
For shop owners buying ads, they'll still need to provide statistics of view, clicks and conversions and that needs tracking. So that's not different from google. Apple claims to be the champion of privacy, that's just hypocritical. Just check the apple Advertising & Privacy page.
