Yeah. Same here. I worked with OSGi long before I used REST and microservices. To claim that OSGi somehow pioneered this stuff is both arrogant and ignorant. Sure OSGi and microservices share some similar concepts but they are both implementing ideas commonly found in distributed systems. The author just comes across as bitter. I liked OSGi when I first encountered it but for some of my colleagues it was a lot of overhead to do the simplest things. Either they had to learn it all conceptually or they have to rely on a lot of magic from the tooling. I feel that to really understand OSGi you had to know a bit about the nuts and bolts of Java and its internals. This is not common especially even among Java programmers. The advantage of REST microservices is that most developers understand REST and HTTP, etc. People have a much easier time getting REST and microservices (although you really need to know distributed systems to not get yourself into trouble with some boundary cases and failure modes).
