An exclusive poll for Axios by SurveyMonkey found that Facebook's favorability has plunged in the last five months.

The big picture: In the Axios/SurveyMonkey poll comparing views in October with last week (2,878 adults in the U.S.; error estimate: 2.5 points), Facebook's already low net favorability (favorable minus unfavorable) dropped twice as much as the other tech giants.

• Facebook fell 28 points, compared with 13 for Amazon, 12 for Google, 10 for Apple and seven for Twitter. Uber, Tesla and Lyft ticked up, bucking the trend.
• Facebook's raw favorability rating was 48% last week, down from 61% in October.
• Google's latest raw favorability was 78%, Amazon's was 75%, Apple's was 61% and Twitter's was 31%.
• SurveyMonkey points out: "In October, Facebook had more positive than negative ratings by about 2-1; now it’s ... 48% favorable, 43% unfavorable."

Key stat: The negative turn for Facebook is particularly large among Democrats and Democratic-leaning independents, with favorable ratings falling 16 points, from 67% to 51%. SurveyMonkey found more modest fall-offs among Republicans and GOP-leaners (10 points) and pure independents (eight points).

But, but, but: The mistrust is focused on the companies, not on technology. The vast majority of those polled (72%) still say tech has a positive effect on society.

Our thought bubble: The poll shows a huge drop for Facebook (and Twitter and Google). But remember these are free services. People talk a lot about leaving, but we suspect most want what these companies are offering. 

• We'll be watching to see if these drops in favorability mean fewer users (like if #deletefacebook gains traction).

Be smart: If Facebook were a political candidate, this kind of swing in public opinion would provoke a swift, massive response. For Facebook, that process has just begun.
