The network Twitter demonstratively banned the accounts of RT and Sputnik from advertising. The decision can be only be explained by pressure from the [U.S.] government and intelligence services.
While the findings of the intelligence community partially influenced Twitter’s decision, no evidence of any pressure from the government has emerged, and Twitter is a private company in an industry that has taken the public stance of resisting government pressures. Twitter’s statement says: "Early this year, the U.S. intelligence community named RT and Sputnik as implementing state-sponsored Russian efforts to interfere with and disrupt the 2016 Presidential election, which is not something we want on Twitter. This decision is restricted to these two entities based our internal investigation of their behavior as well as their inclusion in the January 2017 DNI report."
