I deleted 16 years worth of my ‘content’ across 6 handles and moved to Lemmy/kbin. When I do go back to check on Reddit, it’s easy to see that many of the better contributors are gone, the quality of comments and posts, as well as the voting on posts, has greatly diminished. Some subs barely have anything in their ‘new’ queues.
Google is fine for most people, but it shouldn’t be the sole backup. If you don’t have (at least) 3 separate instances of a backup, you don’t really have a reliable backup strategy. Preferably an onsite hard backup, an offsite hard backup, and a cloud backup.
