I think you're confusing the company formerly known as Snapchat, now called 'Snap Inc.' with the 'Snappy' package manager (hosted out of 'snapcraft.io') which makes linuxy packages called 'snaps'. The two are unrelated.
I also got confused (I was wondering "who is Snap, and why is he investing in Google"), Snap is not that popular at the news sites that I read (which is mostly Hacker News :), at least after their name change.
