Google can do this at any time for any reason to anyone.

Backing critical stuff up to online accounts can be a way to avoid loss in the event of hard drive failure, theft, fire, malware, etc BUT it shouldn't be your only copy, you should keep a local back-up or a back-up with another unrelated company.

The cloud is just someone else's computer. Your Google documents and such are not immune to being lost, it's very improbable but as seen here things and shit can happen. As companies adopt more AI moderation there will be more false flags in addition to genuine ones that result in total losses for people due to their "risk score" rising too high.

Keep local copies, never put all your eggs in one basket.
