Most employees of AT&T had no idea it was even going on, so to lump every AT&T employee into the same batch of "you're bad because th company you work for was doing X" when they had no idea the company was doing X isn't really fair.
By the same vein, Stephen Miller trying to round up and cage innocent civilians just trying to live their life is a very different part of the government than Suzanne at NASA who's trying to better the future of mankind. To act as if there's no distinguishing between the two is just silly.
Whether you have an issue with the specific term "deep state" I'll leave be. But please don't try to oversimplify large organizations. The higher up the chain the more responsibility you can place for what the organization as a whole does, but the reverse isn't true when speaking outside of their specific area of ownership.
