I'm sure this has been asked and answered before, but why do companies acquire startups just to shut their product down within a year so often? Is this just an acquihire? Or do big tech companies just play whack-a-mole with startups, buying any out with interesting products just to make sure they don't one day turn into competition?

For the $100+ millions Microsoft payed,they got the team, the tech and the opportunity to move the sunrise users to use their products.

Sunrise best capabilities are likely being built into outlook, they have a team that they know can execute and a percentage of sunrise users will move to outlook.

I only installed sunrise last week (when I moved to Android) but I found it a bit odd that I was using a different calendar app. I came from Windows Phone where messaging and calendar was baked in really nicely. So far my Android experience isn't as good but maybe outlook with sunrise will complete this circle for me.
