How thin is “thin”? If I build a chat app on top of Redis, is it safe? There’s a tutorial on the Redis website: https://developer.redis.com/howtos/chatapp/ — is it a sign that it’s too simple to be distinct?

Or I can just migrate my app to Valkey and be sure I’m safe from lawyers.

Its a chat app not a data store, so it fails the "primary purpose" test so its safe: its pretty obvious that a chat app serves a different purpose to a key value data store.

Nothing is definitely "safe from lawyers". In some ways BSD is less safe than SSPL - no patent licensing clauses for example.
