Facebook, Google, Twitter and others have said they won�t block people posting links to a protest against the Dakota Access Pipeline near Cannon Ball, North Dakota.
But some have already started taking down the posts, and others are still sharing them, according to news reports.
The New York Times reported that Facebook blocked a number of posts, including ones that shared images of protesters and an image of a gas station.
Twitter said that posts containing the words, “We won�re coming back to North Dakota, we’ll take our power back” were not allowed.
Google said that it would not remove posts that include the words “No DAPL.”
The Washington Post reported that Google and Twitter had already removed some of the posts that contained the words.
The Times said that Google, YouTube and Facebook have been taking down posts that contain the words.
“It�s pretty clear that this is not what democracy looks like,” said Marc Rotenberg, a former State Department official who advised President George W. Bush on global climate policy.
“The whole point of having an open marketplace is to let people share ideas, ideas that might help people,” Rotenberg said.
Rotenberg said that the companies� actions were consistent with their own policies and that it was not surprising that they would do that given their strong public statements on climate change.
The companies say they are taking a stand against climate change because they believe it will negatively impact the economy.
