Yes but when the ultimatum is something along the lines of "follow my lead or I won't be your friend," people tend to feel rather resistant, wether the ultimatum is spoken or unspoken, intentional or not.
I can tell you right now, I don't react well to ultimatums.
The worrying thing is that ENTJ's might be sending off this message unintentionally, by going towards people who follow, and going away from people who don't. I know I try hard to control this but honesty I just like people who follow much more. I'm the nicest guy with people who do, and that person becomes like family... and on the other hand I need to take distance from people who resist. Sounds awful but I'm telling it like it is.
