It's not a guess, it's much worse than a guess. It's inherently biased: it collects data from people who care downvote count to the extreme only. They care the count so much that they installed an extension specifically for it. Think about it.

It's not randomly sampled from the whole demographic. It's not SteamDB*.

It's not different from getting "the opinions of generic US people" from the comments below Biden/Trump's tweets.

* Technically SteamDB has a bias too: it samples from the players who made their profiles public only.
