The United States (famously) has stronger free speech protections and weaker libel/slander laws, yet seems to have less of an issue with tabloids. Is there maybe more of a divide between what's alloweable for "public figures" versus private citizens? Or maybe even our right-wing rags are more skeptical of the government? I don't know what the difference is, but you seem to see less of this sort of thing, gross as our tabloids still are. Maybe it really is just a cultural difference somehow.
The US equivalent of a tabloid would be Fox News, right? #1 most viewed media outlet, argued in court nobody would take them seriously yet they do, current self-destructive regime wouldn't be in power without them? They're much worse.
The US tabloids are awful. Any checkout isle at a Walmart, Dollar General, etc is just littered with them, right next to the disposable lighter packs and chewing gum.
But nobody reads them in the US[1], and many are about celebrities or cryptids or what-have-you rather than current events or private citizens. There's definitely a cultural difference here.
