I don't have an HTC but I got interested, do you have to contact support or anything similar to get a code to unlock the bootloader/root the device (kinda like Windows XP activation)? I've only rooted a Samsung Galaxy Ace and all it took was to boot into recovery and run a zip file. Sorry for any mistakes regarding terminology.
No I still have an old HTC Developer account I created years ago. And I can still generate tokens. Only issue is that people can't create new HTC dev accounts.
