To expand: the paradigm of only offering +1 and not -1 is, to me, akin to the whole "everybody's a winner" problem; if I go to a product page, and all it has is a +1 button, and the 'score' is 0, then there's absolutely no context to justify the score.
Is it that the product is brand-new (and/or just added the +1 button), or conversely, is it that the product is horrible and though the +1 button has been there a year, nobody has clicked it?
Whereas if I were to visit and I could see that the score was -1000, then that would give me a very good indication that the product (or some aspect of it) sucks.
Then of course there'd likely be situations where there'd be a mix, and so it'd be good to see a representation that took all votes into account, e.g. [+1000/-500]; with that, I could see that the sample size is moderately sufficient (1500), and that most people approve -- but that it's not without detractors.
Mostly, though, I'm tired of "everybody's a winner".
But lets be real here, no brand is going to let FB/google/socialwhoever put a -1 button on their marketing page. And all the really matters at the end of the day is what the money decides, not you, as it's your eyeballs being sold. BigCo would never pay for the opportunity to have anyone to slap a -1 on their beloved flawless products.
