The author seems to be assuming that microservices are only used to break down a single application into different services, in which case their arguments are valid. If you instead consider that a single service can in fact be used by multiple applications, most of their arguments are plain wrong.

For example: >Why would you ever want to allocate more resources to one particular part? It’s not like the other parts will eat up the extra resources. If your system needs more RAM, it needs more RAM. Why would you care about which part needs more RAM?
