In my experience, this is by far the largest group. Then they build a distributed monolith and cause a giant mess, like the OP was describing. I really wish people would jump off of the microservices bandwagon, because so very few on it actually understand microservices at all, or have the skill set to make them work.
Well, one issue is that everyone seems to have a different picture about what a microservice is and everyone also thinks they have the correct understanding.
