I think OP's point was that if your company provides a service, and runs 10 containers to do it, then each container provides 1/10th of the total functionality of the service and is therefore a "deciservice". The joke being that you then can't say you use "microservices" until you've got 10^6 of them.
I meant division of functionality rather than horizontal scaling. For instance, all of Netflix consumer facing features making up the 'Netflix app' is a full 1.0. If we subdivide the functionality into pieces the number of functional pieces determines the fraction of the whole application it provides.
But.. if you have 10^6 total instances I don't think anyone would object to you calling them micro.
