It's a tool. Tools can be used for good or ill. This tool is the hotness right now so it's quite overused in a lot of poorly fitting situations. This particular usage serves no socially beneficial purpose and needs to be regulated into non-existence (we at least shouldn't pay people to do it). The tool is still useful for a bunch of things but some people get irrationally defensive if you critique their favorite tool. It's a good tool and it's a flawed tool - like every other tool.
