In a world where signed messages are standard, people might be more skeptical of random assertions.
Rumors, which can't be expected to be signed by the correct authoritative source, would still spread as usual though, which is what cointelegraph would continue doing.
"SEC approves blackrock Bitcoin ETF" might not fly in such a world, but "Anonymous source says blackrock Bitcoin ETF approval imminent" can't really be stopped without making better people lol
