And Greenwald, bless his heart, is just wrong. Or rather, he's applying a correct principle to a situation it just doesn't apply to. Just because it's a noble principle of a society to protect freedom of speech - or that it's noble for actual journalists (not Elon Musk) to resist editorial pressure - doesn't mean that randos saying reprehensible things on Twitter is noble. Even if one of the randos owns the company.

So Twitter was free of randos saying reprehensible things before Elon bought it?

While there is journalism happening on Twitter, whatever Musk and the antisemitic randos whose retweeted posts landed him in that interview chair are doing isn't journalism.

Not the point.
First off, MediaMatters rigged those posts with the specific intent of driving advertisers off. Those advertisers - woke outfits like Disney and Apple - have been waiting for an excuse to virtue signal their way off the platform and thus they ran with it.

Musk is *enabling* journalism. Twitter was a censorious pit where conservatives were throttled, shadow-banned or flat out censored Because Rulez. Now it's a level playing field and people like David Brock and the editorial boards that masquerade as news agencies don't like that. At all.

So Elon is perfectly correct to call out Apple, et als. attempt at going along with MediaMatter's boycott/blackmail scheme ("Nice platform you have there, be a shame if anything happened to it..")
