While Musk is supposedly for free speech (as long as not critical of Musk), maybe Lake's legal team pointed out that being able to say dumb stuff is not the same as being safe from the consequences of libeling others?

From linked Hill article:
Defeated Arizona gubernatorial candidate Kari Lake (R) deleted a tweet accusing the judge who dismissed her election challenge of integrity violations.
The tweet, which was posted early Monday morning, suggested the founding partner of a law firm representing Gov.-elect Katie Hobbs (D) emailed Maricopa County Superior Court Judge Peter Thompson what to say as he authored the dismissal.
The Dismissal of Kari Lakes Election Lawsuit Shows Voter Disenfranchisement No Longer Matters @Rach_IC:Legal experts believe his decision [by Judge Thompson] was ghostwritten, they suspect top left-wing attorneys like Marc Elias emailed him what to say, the now-deleted tweet reads.
It might be amusing, even helpful, that Elon Musk's largess re GOP/GQP/MAGAs posting swill could blow up in some cocky faces as they mouth off without regard for consequences beyond Elon's playground.
