My personal favorite is "Move off of AWS MSK". No big deal - we just fire up some kafka brokers and and zookeeper nodes in ECS! All we gotta do is run several more supporting services to keep the cluster healthy and deal with the nightmare of Apache security ourselves.

As far as I'm concerned MSK is cheap - one broker is priced roughly same price as 2 equivalent EC2 instances. And you don't have to worry about zookeeper at all!
