Microservices take an organizational problem:

The teams don't talk, and always blame each other

and adds distributed systems and additional organizational problems:

Each team implements one half of dozens of bespoke network protocols, but they still don't talk, and still always blame each other. Also, now they have access to weaponizable uptime and latency metrics, since because each team "owns" the server half of one network endpoint, but not the client half.
