I had a quick look at the transcript of Ben's talk, and it seems that one of his main issues with microservices which share the same code base (and therefore dependencies) is the overhead of upgrading their dependencies. I do understand that in some cases this might be problematic. However, if the microservices are written using the same language (or runtime), there is a huge benefit of reusing some abstractions. These might include things like validation schemas, serialisation formats, etc. These are the things that most likely would need to be created anyway for every microservice written in a new language. As usual, there has to be some balance in the amount of coupling between microservices. But there is nothing inherently wrong with reusing code between them. I think the most important factor in a microservice ecosystem is having well defined protocols and APIs.
