It exists, but it is being selectively ignored by those in charge. Don't assume it will automatically defend you, especially not pre-emptively:

And when, rarely, they do apply, you get no restitution or relief.
Is there any significant difference where the law gives you fewer rights in the EU in this regard? Very unlikely that in the EU some SWAT team will knock down your door because someone anonymously told them on the phone you're dangerous, kill you, and suffer no consequences.
> but because in the USA you have some very strong constitutional rights that are really hard to bypass
Other than the right to have guns, which keeps everyone happy and gives the SWAT team a legitimate reason to go in guns blazing I'm having a hard time finding some right that isn't routinely subject to some major exception. Especially when you ultimate authority on the constitution is staffed by yes-men.
You might get a few more of them. Recently a bunch of French people received jail time for repeatedly posting how the president was a pedophile and his wife was a man. Because, you know, harassment is illegal in many European countries. But the only obligation by the service provider, if asked, would be to delete the posts and give the user's IP address.
The EU Digital Services Act is actually a much wider liability shield than the USA's Section 230.
I never heard of American presidents going after individuals on Twitter or other platforms. Neither Obama, nor Biden and also not Trump who is receiving so much hatred and bad words, without even touching the assassination attempt. Which is probably the only reason why they threatened to go after people, but that seems to be understandable - and I think that's the line you should not cross in a forum/platform.
The mindset is completely different.
Even during the Roman Republic people could make fun of or heavily insult politicians, and also with ugly things that we could never say today. Even Julius Caesar was mocked heavily (the famous "every woman's man and every man's woman")
...unsurprisingly, this changed when the Republic ended and the Empire started.
And here we're today thinking about our sensitive politicians :)
The country with the worst “bad opinion, police comes knocking” is the recently seceded UK.
And I guess Germany has something against nazism?
I guess what the OP meant is that in EU you might have the police knocking at your door for some reasons you don't have in the USA, not because they don't have data about you, but because in the USA you have some very strong constitutional rights that are really hard to bypass.
Twitter, Tiktok, etc could never be created in the current EU.
