I agree and don't agree. There are quite a few 'popufurs' out there who are indeed as you described, but there are also quite a few who get that 'title' without wanting it and all the negativity that comes with it. They simply became popular in a variety of ways.
For example:
Saving up for a detailed, expensive fursuit. You really want to have a fursuit made by a particular fursuit maker. Their work is like artwork, and when wearing it you will -whether you want to or not- be associated with this maker. You might simply like their style of fursuit-making as it brings out your character in the best way possible, but people will know you spent a lot of money (and time) into getting that fursuit from that specific builder.
A lot of people won't care about the person inside the fursuit or the character. They will most likely care about
who made the suit, rather than who is
in the suit.
I've known quite a lot of people (online, real life, fursuiting, not fursuiting) who simply wanted artwork or a fursuit made by someone, but they instead get associated for their potential wealth. They don't want this attention, or at least not that much. And a lot of people want to talk to a lot of people, but then can't, because there are too many people wanting to talk with them, because they are popular. See the conundrum?
A lot have not asked to be popufurs, a lot have not realised any potential consequences.
There are always two sides to a story, is what I'm saying here
