I think qualifies as creating a self-fulfilling prophecy.I must say as this thread is about actual play experience, I haven't heard from many people you have actually played* the game and didn't like it. That should be a good sign.
*By this I mean a min. levels 1-10, preferably up to 20.
There are a lot of great games out there. If you are not enjoying one game, it is trivial to move on to another. Demanding that someone invest that much time (ten levels, much less 20) before their opinion becomes valid is completely unreasonable. Plus, it doesn't matter because not playing the game is not playing the game.
I don't think anyone is disputing that it most certainly does have a niche of popularity. The Venn diagram of people who play 10+ levels and the people within that niche would just be a circle.
You could pick any politician and then say that only someone who has attended 10 of their rallies knows them well enough to judge them. And you would find that this politician is quite awesome based on those you have qualified to pass judgment.

As someone who has been playing RPGs for over 40 years, I know what I like and what I don't. I'm not going to tell other people that they don't know their own tastes. If I tell you I don't like coconut, it isn't helpful for you to tell me that I simply haven't tried your personal coconut creme pie yet. Even worse, if I gave in and tried a few bites and didn't like it, don't tell me I didn't eat enough.....
