I'm not participating but I can understand the backlash - over the past few years I've had plenty of junior developers arguing that we should all be using mongo for everything, because it's "web scale" and it can handle "big data", before they even know what a query plan is. A lot of what we do as developers is, and should be, mentoring new devs, and helping to strike a balance between prudent adoption of new technology and understanding the utility of mature technologies, like SQL databases. It has tested the patience of many competent, pragmatic, experienced developers to have to repeatedly justify the use of standard SQL dbs on applications for which they are completely adequate. So the backlash is to be expected.
