To who, an expert or a journalist? Flat Earthers can beat many people in arguments about the earth being flat, because general science knowledge is not very widespread. I could find plenty of journalists that don't know about, for example, the shadow length thing. The idea that newspapers should only quote truth-speakers does not address the reality of the limited knowledge of the journalists themselves. For them, flat earth theory is a choice between either ignoring everything but the mainstream consensus, or sometimes reporting on fringe groups. Clearly the second option is the right policy, especially because reporting on someone's claims does not imply that the newspaper thinks they are true. It may not be a fact that the earth is flat, but it is a fact that flat-earthers think the earth is flat. It may even be newsworthy.

Good journalists are bright enough to get enough information from enough people, assimilate it, and write it in a clear way for the rest of us.

They might do a 'human interest' story on crackpots like flat earthers, but good ones wouldn't "both sides" that issue, just as they shouldn't with other issues where there is strong scientific consensus, or verifiable facts demonstrating the veracity of one side's claims, and none on the other.

This isn't a new problem, and good journalists are capable of handling it.

Will they get it right 100% of the time? No. But the important thing is that there's a process and they're trying, and they'll admit it if they get it wrong. People get fired for getting things egregiously wrong.

None of that is true for propaganda outlets.

Good journalists will do the right thing no matter the standard policy, it's the bad journalists that need culture impressed upon them. Bad journalists are not good at telling who is right, so that makes bothsideism a good standard policy.
