Why would Google even consider this? They're an advertising company and haven't really made any money from anything but advertising. What would they do with this?
Buying a strategic complement where you can multiply the company's ARR overnight by integrating with your own suite makes sense.
Or commoditizing this complement by offering it for free as a differentiator to competitors (Azure, AWS) would also make sense.
Plenty of options to choose from.
