1). Wikipedia is not a reliable source by anyone’s measure. It is free content which is openly edited by the public. Thus, any topic of a political nature can be crafted by those with an axe to grind. In fact, there are organizations with deep funding (Soros is an example) who are paid to edit Wikipedia in a certain political direction as their entire job.
A good warning sign for possible manipulation on Wikipedia is an updated edit (found at the very Bottom of the entry). Your link was edited on 8/17/2020 at 1600. Hmmm. Not a reliable source for sure until verified elsewhere.
2). You source claims that The PostMillennial is involved in fake news and Russian ties with footnote #1 of the bibliography referencing an example. That example is provided by “Belling?Cat”. Further review of this source which alleges the bad activity by PostMillennial reveals this about Belling?Cat.....(linked)
Again, hardly a reliable source. The source questioning Bellingcat (wikispooks) requires crossberification as well, etc, etc.
There are so many govt sponsored and privately sponsored disinformation sources out there, that you have to be careful. Your Wikipedia source is not a credible one.
