That's not really fair. Google seem to work very hard to provide a first class iOS experience on their own services. No reason to assume they'd shut that down on something they acquired.
Oh, this. Shutting down services is different to restricting services to your own platform. Perhaps you have a point, perhaps Google would hypothetically have decided to shut down Parse had they acquired it, but it's not fair to suggest they'd have limited it to Android.
I disagree. Google is probably the biggest threat to Apple, and Apple is probably the biggest threat to Android, but not to Google. Apple has essentially no web presence, companies that do are a much bigger existential threat to Google.
