Breh, exactly. These guys need to think about it from the perspective of someone running a business. You have to make tradeoffs. A framework may be more overhead, but it helps the whole team to speak a common language. It helps with hiring, because if a person knows the framework you know they can hit the ground running or be changed out with someone else relatively easily. It cuts down on boilerplate and reinventing the wheel. It helps with problem solving because millions of developers have already tackled the problem you're facing. For the vast majority of applications where high performance isnt crucial, a framework as robust as spring is fine. And even then, high performance stuff can be done from within it. There is a reason the shyt is ubiquitous in the industry. (Not saying there are no issues with it, obviously.)
