We don't flock to it, they are forced upon us. Finding TVs that support DP is almost impossible.
Nothing is forced on anyone. If people refused to buy them they would be forced to add other ports.
However as someone who considers themselves fairly techy and doesn't comply with such shitfuckery, I only learned about this last week.
Moving forward I just won't be buying any TVs at all.
Edit: God fucking forbid any of you actually do anything, or even better, refrain from doing anything, besides bitch and moan on the internet.
