I respect their decision to create their own fun in the way they want to do it, but I do not interact with them ICly or even want to be in the same areas where they are roleplaying. I am fine with them on an OOC level, but I am not the type of person to react in a starstruck manner when I see a "famous" NPC. I usually just go "hm" in my head, and carry on with whatever PvE thing I was doing. In fact, I've seen them so much since HW released I usually don't even react anymore?
Luckily, for me, it doesn't come up too much, as I don't participate in large server events for the most part. But for a person who does do a lot of public/walk-up RP, I could see a major NPC being there as a huge distraction for both me and the people I'm trying to connect with. That seems to be the most inconsiderate thing about them, in my opinion. You can individually choose to ignore or engage with them, which is fine, but if everyone else around you is suddenly in a tizzy ICly (or OOCly even), to use a phrase from my FC lexicon: RP is die. And that's not very fun.
So tl;dr: Private RP with famous canon NPCs among friends or other canon NPCs is okay with me entirely. Have fun! Showing up to public events as them is not so much.
