The thinking on display in this thread is something like,

"I needed to add a billing address field to the order flow, so I suggested we use Kafka to process shipping requests. My boss said the form field should turn red if an invalid address was entered, and in response, the team lead objected that Oracle charged too much for MySQL. I checked for a pricing page but found a 'call us' form. The CTO decided to go with Kafka, and told us that landlines are an obsolete platform."
