Seeing that Spain isn't an isolated case, this is being prepared and presented in numerous jurisdictions, I suspect that the current state of affairs, where people can completely sideline mainstream media for propaganda, younger generations don't watch broadcast TV anymore, so I think the way it's heading is not something that governments are wanting to countenance. The problem is that it's a useful tool to undermine democratically elected "wrong" governments, but becomes a problem when the "correct" governments become extremely unpopular and they want to cover up their scandals.
The problem is countries like China and Russia have basically gone down the path that information must be censored, and it's appearing to me, that they have the ability to abuse the free flow of information to some extent. The collective west's value of freedom of speech, appears to be something which the governments don't fervently believe in, as it's constantly under attack, or only something which is nominally uttered, not legally guaranteed (I'm not referring the USA, most other nations in the west don't have a guaranteed right to free speech even though they like to insinuate they do).
Last thing is, traditional media, is becoming moribund, and a lot of money has been invested in those forms. It's no surprise that most of it is dying out, but yet, they're still important institutions, which hold some sort of gravitas particularly by politicians, and invariably a lot of taxpayer money goes to keep them afloat. I think a part of this is to try to introduce barriers to new sources of "information" to protect legacy media in a way. Journalists invariably despise having to admit a mistake, and go to extreme lengths to weasel out of ever admitting they were wrong on anything. Seems to be odd that only now, false information is becoming a problem, yet never seemed to ever require legacy media to place as much effort in a correction, as they did in the initial lie. After all in some jurisdictions it's a tactic to push some sort of lie with the full knowledge that far more people will see it, than the fine print correction.
