This has nothing to do with the speech clampdown, but the general gist of it is true. Most of the cases "cited" by the Telegraph article are several years older than the recent decline in industrialisation.
I put cited in quotes, but it's the usual misinformation bullshit. Niehoff never had his home raided. Two duty officers went to his house to execute a search warrant but on discussion with Niehoff just aborted the warrant realising it was issued for someone who wasn't a threat. Also the reason for the warrant was that Niehoff used far right hate symbols, it's just the shock media who reported it was due to calling the minister a dummy.
The lying fritz story is true, but it deeply divided the country and quite a significant portion of the political spectrum want the law abolished. The problem is the law was created in response to a politician being assassinated.
The problem the Telegraph is facing is that their bullshit isn't working any more. Bullshit is like a drug, not just in the fact it addles the brain but also in the fact that as you're exposed to it you build up resistance to it, much like the smack addict who needs more and increasingly powerful hits of heroin to get the same high, those who live off of the bullshit of sources like the Tele are resistant to the kind of BS it used to print, so they need even more powerful BS to get the same impotent rage.
Much like heroin, make it too strong and you'll flat out kill any new users, so you're not going to get new customers. This is the problem facing much of the right wing media. If they tone it down to get a wider base of readers/viewers they'll lose their hardcore audience to other dealers who serve up pure, grade A, uncut black-tar bullshit and if they don't they'll slowly bleed that audience off without anyone replacing them.
This article is just the US (on /.) is just the cognitive dissonance of American Exceptionalism dealing with the fact things have well and truly gone to shit there. You can't deny it any more with secret police shooting people in the street, disappearing people for allegedly being migrants, the president literally trying to cancel anyone he doesnâ(TM)t like (Conan Obrien, changing FCC licences to 30 days, et al.) not to mention practically running the country by fiat (issuing presidential orders like edicts with a tame court refusing to stop him). So in order to reconcile this fact with the notion that 'Murica Uber Alles, they create a huge fantasy that everywhere else must be worse.
