In general I’m in favor of choice and competition, but I can understand why Apple is reluctant to offer it in this case (beyond just the normal anti-competitive behavior, which we’ve all come to expect from the big tech companies).
It’s funny to me how many people still think Google is the only maps game in town, and that just isn’t true. Apple Maps is a very strong contender these days, but it can’t seem to shake its reputation from 10 years ago.
Personally I can’t stand using Google maps. It’s poorly designed in a way that impacts readability and usability, and it’s more interested in showing me a business that paid for placement rather than the locations I’m actually searching for. Whereas Apple Maps was designed with readability as a priority, and I’ve found the map data to be equally reliable. (Perhaps the one exception to this is data that’s crowdsourced, like a shop’s opening hours, but that’s less important to me than being able to find it in the first place.)
