Seems to me to be yet another way to try to control people, and what they do. I am not too sure what the effect would be, but I could see a lot of freelancers trying to create workarounds by becoming ever more specialized in what they do; relabeling their skill set. If a company already has technical writersl you stop being a technical writer and declare yourself some kind of "specialist" with a narrower focus than most companies would have on staff.

Having worked long and hard for autonomy, the prospect of becoming an employee is not appealing.

Bright Blessings!
