My comment this day detailed the channel and associated 'merch' store, their places of businesses and so on.
This is NOT limiting info sources, in any way. It is the inverse, expanding the info about info sources.
Your point is that they are illegitimate because they try to generate income. Which every other news source does too, if only by collecting subsidies from their state owners.
Which is an obvious implicit preference for these state or sanctioned sources.
