Yeah, that would be my answer as well. I actually forgot to mention that - Snowflake and the like store data away from compute so no matter how you misconfigure clusters (though Snowflake isn't really that configurable) the data is safe. Messing up database that stores data locally means the data is gone - and that makes all operations like resizes and upgrades much more scary.

But of course the local storage is much faster. Tradeoffs.

I know ClickHouse Cloud uses S3 as well, but I don't know much about it, so I don't want to comment on it.
