Google invest heavily in securing computing generally, from creating the secure browser Chrome because the alternatives at the time were very insecure to a big paid team of security researchers (recent successes include discovering Spectre and Meltdown) to creating secure operating systems to possibly eventually replace Android and ChromeOS. A lot of security-interested programmers think it easier to secure a small microkernel like Fuchsia than to secure the older generation of operating systems and the baggage they have acquired. Google want everyone to trust the Internet. If consumers are scared to shop online, Google dies. This is why they put so much effort into securing it.
