Why would you say this? It's incredibly offensive, and adds nothing to your argument. A full stack dev might not be as good as a specialized dev in any of backend / devops / frontend, but that's just the price you pay for being a generalist. That doesn't mean they 'pretend to be able' to do things.
I keep seeing it as "I don't have any support and am forced to do a number of things poorly." Sometimes it unfortunately comes with a gross misunderstanding of the needs of some part of the stack.
I partly agree with this. Although I'm convinced there are actually people who CAN do a lot of "this stuff" quite good; I'm convinced that most of us mere mortals would be moderate in some of these at best while struggling with the rest.
