A couple of random thoughts about Messages in iCloud:
- People are saying this is less secure because a backup key is stored in your iCloud backup as Apple can get at your Messages if compelled with a subpoena. But if you have iCloud backup enabled, can’t they do that anyway, as the Messages SQLite database is part of the backup?
- The other accusation I’ve seen is that Messages in iCloud will increase your iCloud data usage and therefore is a good way to encourage people to buy storage. But this isn’t really true, is it? The messages stored in iCloud would otherwise have ended up in your iCloud backup instead. So if you have multiple iOS devices this could actually reduce your iCloud usage. The only reason it should increase it is if you import a long message history from a Mac (which I actually did, go figure).
