Kyiv Post has publicly received funding from the US state-backed National Endowment for Democracy. Allan Weinstein, cofounder of the National Endowment for Democracy, said in an interview with the Washington Post"A lot of what we (the NED) do today was done covertly 25 years ago by the CIA."
Not sure if a news source backed by what is, by their own admission, the public-facing branch of the CIA would be considered “reputable.”
According to the New York Times, the NED has been caught funding a opposition groups in France to undermine the ruling party. The NED was also implicated in helping to fan the fires of the Arab Spring.
ProPublica has this to say: “The National Endowment for Democracy was established by Congress, in effect, to take over the CIA’s covert propaganda efforts. But, unlike the CIA, the NED promotes US policy and interests openly.”
I see no reason to doubt the numbers from the Georgian group that Kyiv Post cites, but that is in spite of it being reported in the Kyiv Post, not because of it. NED-funded sources are literally spreading propaganda, and any source that’s willing to take money from the NED is showing a willingness to spread propaganda.
