Looking at slide 6: Reza, come on. How can you claim your Spring code example is relevant?! You can find this XML hell only in legacy projects, similar to those which use J2EE EJB 2.1.
That's OK comparing the code at slide 6 to EJB 2.1 deployment descriptor. Or to compare code at slide 8 to Spring Boot/Annotations/Groovy config. But what you do, comparing 6 to 8 is just cheating. It will probably work for you when preaching to people who never used or seen Spring in their life, but doesn't winning by FUD make your victory a bit bitter?
I mean, we (JFrog) are in a same kind of a bitter competition with Sonatype. I can speak for myself, the last type of win I would like is winning by FUD. That's why we collaborate on an open comparison, each company maintaining its own column. Just let the best product win.
