Both viewpoints exist, loudly. You'll find plenty of people today that say that the Tether stuff is fine and completely ordinary, and if it hasn't popped by now it probably won't. (Hell, you could read my original comment in this thread that way.)
What changes is which side you look at. Think of it like a Rorschach test: there is no truth, but there's a smattering of contradictory evidence that can be interpreted both ways. Your brain can't deal with the contradiction, and then picks a side based on the preponderance of evidence it sees. It can flip sides if strong new evidence comes out, but in general the brain discounts evidence that contradicts its initial hypothesis and amplifies evidence that confirms it.
