What critical functionality are you thinking of?

We used FOSS Kafka for yonks without hitting any limitations - At one point we were looking at Confluent Replicator, but decided it was just easier to go with Mirror Maker 1 (and you know, no massive licensing fees) - and Mirror Maker 2 largely emulates Replicator in terms of functionality.

I'm aware of a few other things like the MQTT KC Connector, but that was never part of Kafka in the first instance, it's something that Confluent built for paying customers.

And I could argue that the StreamNative "critical functionality" that they lock away behind enterprise agreements is "quick bug fixes for the many bugs we're still finding", if I was feeling mean spirited.

But anyway, it seems your preference for Pulsar is due to Confluent, but they're not the only ones offering managed Kafkas - AWS, IBM, RedHat, etc. etc.
