Looks right. There isn't much of a trail here (the wiki page is relatively new and mostly created by one individual), but I'd buy the general story. They do sound partisan, if not for their history and conflict with the Kremlin. I don't know that this is the case, but given the prevalence of Civil Society Organizations and NGOs in the form of news media fronts created inside Russia and the Baltics by the allies and the recent cleanup of these installations by the Kremlin - properly or no the Meduza team was likely seen as proxy political voices.

Thank you for the research.
