This post was on the frontpage. Now its not even in the first 3 pages. People really think post ranks are not controlled by someone ? I know there are formulae to calculate the post rankings. But I smell BS.
If many individual comments receive lots of upvotes and lots of down votes, for example, that's a signal the topic is controversial. The algorithm automatically penalizes controversial discussions, regardless of what the topic is, because its goal is to maximize the number of "good behavior" discussions, not the number discussions.
Stripe, like US politics, is highly polarizing. You don't have to read hard into this page to see there are strong disagreements on whether Stripe is good or bad. The algorithm detects those disagreements generically (with no care for the company or topic involved) and penalizes the page.
