That thoroughly misses the point. They could do both. There is zero reason to shrink the addressable market other than Apple not wanting to play with others.
We may not agree (and I don't agree with Apple's move here) but it's hardly surprising that they would shut it down for their direct competitor platform.
Let's not forget that it is/was a paid subscription on Android, so offering it for free on iOS and keeping paid on Android would still give them a significant edge. Somebody else in this thread mentioned that Shazam is still available on Android even after the acquisition, so it's definitely not as obvious as you suggest.
Not only that, but presumably if Dark Sky becomes the base for the iOS default Weather app, then there won't be a DS standalone iOS app. So they wouldn't just be maintaining a port, it would be an entire Android app with no iOS equivalent.
They could have just bought the developers to work on Product X at Apple and don't want them wasting their time on something else. That's how a lot of Tech M&A is done...
Its very hard to maintain an Android app to the same quality that people expect from Apple. I can see why they'd want to shrink that headcount or redirect to a more productive endeavor. As a bonus, Apple devices get a better weather app than the competition. The API part doesn't make as much sense, since they could make a pretty penny reselling that data without as much support burden.
apple has 100 billion dollars in the bank, funding a world-class android team should be possible if not desirable for them as they transform more and more in to a services company
It's not about money, or else Google's YouTube app wouldn't be a massive pile of failure on iOS, tvOS, etc. It's about being able to manage teams and maintain direction.
thanks for writing the exact same thing as the person next to you, but im not talking about "just throwing money", i'm talking about what they do when their ever-increasing war-chest stops increasing and they actually have to build things for people who can't afford their ever more expensive hardware. If apple thinks that they can continue running their ecosystem this way, i'm gonna be cackling in a few years.
