You forgot to mention that besides royalties, the main reason HDMI is used in consumers electronics is that it also streams audio with CEC as apposed to Display Port that only does video.
For most consumers, plugging in just one cable that does everything is a lot more convenient.
Edit: sorry, didn't know DP can also stream audio, my bad
