I don't think Jeff comes across as angry.  He's simply pointing out that
ScyllaDB isn't a drop in replacement for Cassandra.  Saying that it is is
very misleading.  The marketing material should really say something like
"drop in replacement for some workloads" or "aims to be a drop in
replacement".  As is, it doesn't support everything, so it's not a drop in.
