Why do you say that? Wikipedia is vastly different from anything I’d normally recognise as news media(I guess that’s what you mean?). It puts content up front (except when asking for donations). It shows how the sausage is made (you can look at talk pages if you really want to). It sources claims. I guess at some point it’ll take a turn for the worse, but it’s nowhere close to there yet from what I can see. Am I missing something? I guess you could say that it’s part of the ecosystem in that it trusts it and news sources are an integral part of its fact-checking process, but I don’t see that that makes it resemble too closely the sources it uses for fact-checking. And companies use it for PR\allow-washing, which isn’t great. And subject-experts express frustration in getting their edits reverted by idiots. But, it’s still recognisably wikipedia from the old days. I don’t see how you get to “not much different from any other part of the media ecosystem”.
