European Commission President Jean-Claude Juncker said Thursday that he sees companies like Google and Amazon as a danger because of their potential to manipulate their power.

Speaking to three popular YouTubers in a live interview hosted by Euronews, Juncker responded to questions asked by their followers.

Juncker noted that the huge amount of data held by U.S. tech giants gives them a "potential for manipulation," in response to a question about what he thinks of companies like Google and Amazon.

He said that he is surprised that the people who ask these questions are devoted customers of the aforementioned companies.

"They are criticizing these companies but at the same time they are customers of these companies so they are helping them make money" Juncker said.
