Just an fyi in case you weren't trying to snipe on purpose, but there haven't been any data loss "issues" (e.g. stupid decisions by Google) with Apps for several years now.

That said, if I were using Firebase I'd be concerned, too. Google is well known as a place startups go to die, or morph into something The Borg wants rather than something aligned with the startup's original vision and the expectations of their paying customers.

Good luck and godspeed!
