Overton window

There's a difference between socially unacceptable and "straight to jail".

You mean like Assange and Manning?

Manning not only released documents that were under her care as an intelligence officer, but also broke into other systems. Regardless of whether you support what she did, she did so knowing the consequences of breaking her oath. In doing so, she made public wrongdoing, but also exposed sources that the US had promised would be kept safe.

Assange... well, that feels more like a case of karma. The Obama/Biden administration declined to indict him in relation to the Manning leaks. He then screwed with the 2016 US elections, blatantly stoking conspiracy theories, laundering Russia's hacks in service of Trump, and coordinating with the Trump campaign to time releases to blunt at least one scandal. In return, the Trump administration indicted him. I don't fully understand the case, so I won't comment on it.

Compare that to investigative journalism in general in the US. Journalists can publish pieces that are extremely critical of both the government and corporations. High up people regularly are dragged down from their perch by an enterprising reporter. Maybe newsrooms aren't as well staffed as they used to be, but it's not in the same league as countries like China, Russia, and Venezuela that lack anything resembling a free press.
