I've gone into this earlier in the thread, but a major difference is that journalists typically will follow a double source or even triple source rule, which means you need at least two verifiable (though they can remain anonymous to the public, but verifiable to the reporter), disconnected sources that are saying the same thing without any cross-contamination. This is proper reporting protocol. I hear plenty about games, plenty of it correct in the long run, but I don't print it because I can't get the two sources together.
Obviously people on blogs or youtube influencers or whatever aren't necessarily beholden to these rules. In fact, nobody is, but the bigger and more 'professional' an outlet is the more likely they have rules around stuff like this in place.
That's exactly my point. If professional games journalists can't find any other verifiable sources to support the leak, then there isn't enough evidence to support the claim.
