I'm not claiming that at all. That study is based on what FB has decided it would rule was "fake news". And FB has clearly been proven to be biased in its blocking and censoring of conservative groups or pages, and highly supportive of liberal and progressive groups. Once again as evidenced by their allowance of the Obama campaign to use data they admitted they wouldn't allow other groups to do. Which is why they are blocking Cambridge Analytica now.
"FACEBOOK REPRESENTATIVES TOLD BARACK OBAMA’S 2012 CAMPAIGN THAT THEY HAD BEEN ALLOWED TO USE THE PLATFORM IN WAYS THAT WOULD HAVE OTHERWISE BEEN PROHIBITED, BECAUSE FACEBOOK WAS “ON OUR SIDE,” ACCORDING TO EXPLOSIVE CLAIMS FROM OBAMA’S FORMER DIRECTOR FOR MEDIA ANALYTICS, CAROL DAVIDSEN.
They came to office in the days following election recruiting & were very candid that they allowed us to do things they wouldn’t have allowed someone else to do because they were on our side."

Did you even read the study?
Why am I even asking this?
Please tell me where the researchers said that they used FB's definition of "fake news":
From the study.....
"STUDY SAMPLE AND METHOD
For this study, a seed of known propaganda websites
across the political spectrum was used, drawing from
a sample of 22,117,221 tweets collected during the
US election, between November 1-11, 2016. (The full
seed list is in the online supplement and available as
a standalone spreadsheet.) We identified sources of
junk news and information, based on a grounded
typology. Sources of junk news deliberately publish
misleading, deceptive or incorrect information
purporting to be real news about politics, economics
or culture. This content includes various forms of
extremist, sensationalist, conspiratorial, masked
commentary, fake news and other forms of junk news.
For a source to be labeled as junk news it must fall in
at least three of the following five domains:
• Professionalism: These outlets do not employ
the standards and best practices of professional
journalism. They refrain from providing clear
information about real authors, editors,
publishers and owners. They lack transparency,
accountability, and do not publish corrections on
debunked information.
• Style: These outlets use emotionally driven
language with emotive expressions, hyperbole,
ad hominem attacks, misleading headlines,
excessive capitalization, unsafe generalizations
and fallacies, moving images, graphic pictures
and mobilizing memes.
• Credibility: These outlets rely on false
information and conspiracy theories, which they
often employ strategically. They report without
consulting multiple sources and do not employ
fact-checking methods. Their sources are often
untrustworthy and their standards of news
production lack credibility.
• Bias: Reporting in these outlets is highly biased
and ideologically skewed, which is otherwise
described as hyper-partisan reporting. These
outlets frequently present opinion and
commentary essays as news.
• Counterfeit: These outlets mimic professional
news media. They counterfeit fonts, branding
and stylistic content strategies. Commentary and
junk content is stylistically disguised as news,
3
with references to news agencies, and credible
sources, and headlines written in a news tone,
with bylines, date, time and location stamps.
Sources of junk news were evaluated and reevaluated
in a rigorously iterative coding process. A
team of 12 trained coders, familiar with the US
political and media landscape, labeled sources of
news and information based on a grounded typology.
The Krippendorff’s alpha value for inter-coder
reliability among three executive coders, who
developed the grounded typology, was 0.805. The 91
sources of political news and information, which we
identified over the course of several years of research
and monitoring, produce content that includes various
forms of propaganda and ideologically extreme,
hyper-partisan, and conspiratorial political
information. We tracked how the URLs to these
websites were being shared over Twitter and
Facebook (see online supplement for details).
Specifically, we computed the coverage and
consistency scores for each group. Coverage of a
group refers to the percentage of all propaganda
domains identified in our junk news sources list that a
group posted links to. The Consistency of a group
refers to the percentage of the total of number of links
to all the propaganda domains identified in our junk
news sources list, that is shared by the group. A high
value for coverage shows that the group is sharing a
wide range of propaganda, while a high value for
consistency shows that the group is playing a key role
in the spreading of such propaganda. Coverage and
consistency scores were calculated from the number
of links shared from the groups to the junk news
sources."
